IMR Distinguished Lecture – Sanjay Krishna, University of New Mexico @ E100 Scott Laboratory
Apr 12 @ 9:45 am – 11:00 am

Antimonide Materials for Mid-Infrared Photonic Detectors and Focal Plane Arrays

Sanjay Krishna

Director, Center for High Technology Materials, Professor and Regents’ Lecturer, Department of Electrical and Computer Engineering, University of New Mexico


Infrared imaging (3-25mm) has been an important technological tool for the past sixty years since the first report of infrared detectors in 1950s. There has been a dramatic progress in the development of infrared antimonide based detectors and low power electronic devices in the past decade with new materials like InAsSb, InAs/GaSb superlattices and InAs/InAsSb superlattices demonstrating very good performance. One of the unique aspects of the 6.1A family of semiconductors (InAs, GaSb and AlSb) is the ability to engineer the bandstructure to obtain designer band-offsets. Our group ( has been involved with the vision of the 4th generation of infrared detectors and is one of two university laboratories in the country that can undertake “Design to Camera” research and realize focal plane arrays.

My talk will revolve around three research themes.

The first theme involves the fundamental investigation into the material science and device physics of the antimonide systems. I will describe some of the challenges in these systems including the identification of defects that limit the performance of the detector. The use of “unipolar barrier engineering” to realize high performance infrared detectors and focal plane arrays will be discussed.

The second theme will involve the vision of the 4th Gen infrared imaging systems. Using the concept of a bio-inspired infrared retina, I will make a case for an enhanced functionality in the pixel. The key idea is to engineer the pixel such that it not only has the ability to sense multimodal data such as color, polarization, dynamic range and phase but also the intelligence to transmit a reduced data set to the central processing unit. The design and demonstration of meta-infrared detectors will be discussed.

In the final theme, I will describe the role of infrared imaging in bio-medical diagnostics. In particular, I will highlight some work on using infrared imaging in the early detection of skin cancer and for detection of flow in cerebral shunts. Using dynamic thermal imaging on over 100 human subjects, a sensitivity >95% and specificity >83% has been demonstrated. Commercialization of this technology will also be discussed.

IMR Distinguished Lecture Series- Neil Alford, Imperial College of London @ Smith Seminar Room, 1080 Physics Research Building

From Mobile Phones to Russian Dolls to MASERs


Neil Alford, Head of Department of Materials, Imperial College London

Friday, January 20, 2017

9:30 AM

Smith Seminar Room, 1080 Physics Research Building



In this talk we will look at the problem of dielectric loss (the tan δ) in oxides and how this led us to the world’s first room temperature MASER. Why are we interested in dielectric loss? Almost all of us have a mobile phone and dielectric resonators form essential parts of communications systems. The term “Dielectric Resonator” was first used by Richtmeyer(1) in 1939 who showed that a dielectric ring could confine high frequency electromagnetic waves and thus form a resonator. The idea of a dielectric material confining EM radiation dates back to 1897 when Lord Rayleigh described a dielectric waveguide(2) and in 1909 when Debye described dielectric spheres(3). With the astonishing growth in the cellular communications industry the market is now very approximately 2BN sales of mobile phones each year (that’s about 60 each second) the market for microwave ceramics is huge.
One of the key properties is the dielectric loss or tan delta. The inverse of this is called the Quality factor or Q. Imagine a tuning fork. When you strike it, it resonates for a long time – it has a high Q and if it were made from e.g. wood it would be damped severely, would not resonate and have a very low Q. Now imagine hitting a dielectric (like alumina or sapphire) with an electromagnetic wave – a microwave – it resonates and what we need is a very high Q so that we can build good filters. The dielectric loss is limited by the dielectric loss of the material – the dielectric limit – but suppose you could exceed this. This is what we did by some cunning engineering using a Bragg reflector (a bit like a Russian doll) in which the sapphire layers of the Russian doll (called Bragg layers) are not the usual equal thickness but are aperiodic. Remarkably, if the layers are aperiodic in thickness the Q factor rises quadratically to reach extraordinarily high values of Q=0.6×106 at 30GHz (world record)(4).
This result suggested that it might be possible to reach the threshold for masing and indeed we demonstrated that in P-terphenyl doped with pentacene when located inside a very high Q sapphire resonator maser action can be observed. This is the first time a solid state maser has been demonstrated at room temperature and in the earth’s magnetic field(5). Recent work(6) has shown that miniaturisation is feasible and considerable reduction in pumping power is possible by using a strontium titanate resonator which by virtue of a higher relative permittivity leads to a factor of over 5 in size reduction. Importantly, the Purcell factor which is the ratio of the Q factor to the mode volume, remains high and this is a key factor in the ability to exceed the threshold for masing.

Factors Influencing Product Innovation in Solar Energy Markets

Tuesday, February 7, 2017

2:00 – 3:30 PM

Mason Hall, 2nd Floor Rotunda, 250 West Woodruff Avenue, Columbus, Ohio 43210

Registration: Discovery Themes Survey RSVP 




Co-sponsored by the Materials and Manufacturing for Sustainability Discovery Theme focus area, Institute for Materials Research and Fisher College of Business




In 2010, Ardeshir Contractor raised $80M from three US private equity investors and a joint venture with First Solar to build Kiran Energy – a solar energy utility at the forefront of India’s solar energy market.  In its journey, the company examined and deployed multiple innovative products seeking higher performance with leap-frog cost economics and also set early benchmarks in non-recourse project financing.

This talk will focus on both product innovation in solar energy and innovation in sustainability financing.  The size of the solar energy market is significant – nearing an annual investment in solar energy new power plants of $250B.  Solar modules, inverters, monitoring systems, and storage comprise most of this number.  The addressable market for the introduction of new solar technology or product innovation is very large and allows for immense scalability.  The solar market is truly global both in terms of markets and suppliers.


Product innovation in solar energy

The seminar will include a review of effective product introductions, many of which exhibit similar characteristics of product astuteness and a drive to forward-looking performance and commercial targets.  Not all successes have been smooth, some of the leaders have had setbacks including unforeseen technical issues.  The large amounts of investment required for manufacturing and selling implied a constant requirement to maintain the path and story of strong financial returns.  Blending aggressive technology and commercial innovation appears to have worked. It is useful to examine how such dual innovation is embedded in a product offering.


Innovation in sustainability financing

Solar energy components and systems are expected to function for 20-30 years and the overlay of bankability and financing are critical especially for innovative technology.  The long-term nature of the finance and returns – coupled with the very scale of the explosive investment needs – has required the development of new financial market products and market sources.  Very quickly the sustainable financing story has evolved from government and agency support to mainline financial markets.  However, analytical processes and the banking institutions are still retooling for this.  In addition, an asset that functions over such a long term would require financial evaluation and analysis methods that align with its characteristics.  The approach is to describe these efforts, the evolution of sustainable financing and what it implies to product innovation.

Distinguished Lecturer Series – Wayne D. Kaplan @ E100 Scott Lab
Oct 12 all-day

Wayne D. Kaplan is a full professor in the Department of Materials Science and Engineering at the Technion – Israel Institute of Technology, where he holds the Karl Stoll Chair in Advanced Materials.  Kaplan currently serves as the Executive Vice President for Research at the Technion.  He completed his BSc in Mechanical Engineering, and his MSc and DSc in Materials at the Technion after immigrating to Israel from the U.S.  He then spent a year as a Humboldt Fellow at the Max-Planck Institute in Stuttgart Germany before joining the Technion faculty in 1995.


During the past 20 years Kaplan’s research activities at the Technion have focused on the structure, chemistry and energy of interfaces between metals and ceramics, with a focus on the correlation between thermodynamics (continuum) approaches and the atomistic structure and chemistry of interfaces.  In addition to his fundamental research in materials science, Kaplan works on the development of electron microscopy techniques for characterization at the sub-nanometer length-scale.


Kaplan is the author of more than 130 reviewed and archived scientific articles, as well as two textbooks: Joining Processes and Microstructural Characterization of Materials.  In 2006 he received the Henry Taub Prize for Academic Excellence.  He is a fellow of the American Ceramic Society, a member of the Israel Microscopy Society, and was an editor of the Journal of Materials Science (Springer).




Controlling grain size is a fundamental part of Materials Science and Engineering.  While the driving force for grain growth is thought to be understood, the mechanism by which grain boundaries migrate, and how microscopic parameters affect grain boundary mobility, are less understood.  This presentation focuses on the mobility of grain boundaries and how dopants and external fields influence the kinetics of grain growth.


The first part of the talk will address the concept of solute-drag, where conventional wisdom indicates that moving a solute cloud with a grain boundary should either slow down grain boundary motion (e.g. Mg in Al2O3), or not affect it.  Model experiments at dopant levels below the experimentally determined solubility limit clearly show that some adsorbates reduce grain boundary mobility (the accepted solute-drag effect) whereas other increase grain boundary mobility (solute-acceleration).  Reasons for the varying behavior are discussed within the framework of grain boundary disconnections as the mechanism by which grain boundaries move, and current approaches to understanding Gibbsian adsorption.


The second part of the talk reviews model experiments designed to probe the influence of external fields on grain boundary mobility.  As a model system, polycrystalline SiC underwent conventional annealing, and annealing using spark plasma sintering (SPS) without pressure, and the grain size as a function of annealing time was characterized.  From these experiments, the grain boundary mobility of SiC at 2100°C under conventional versus SPS annealing was determined.  SPS annealing resulted in a grain boundary mobility which is three orders of magnitude larger than that resulting from conventional annealing.  This indicates that the same (or similar) mechanism which promotes rapid sintering during SPS also significantly increases the rate of grain growth.  This mechanism will be discussed in light of the “solute-acceleration” effect presented in the first part of the talk.
