Lateral high-quality growth of Si and Ge on amorphous and lattice-mismatched substrates using metal-catalyzed growth

Nate Quitoriano   

Assistant Professor, Department of Mining and Materials Engineering, McGill University

FRIDAY, SEPT. 14, 10:00AM – 11:00 AM

260 Dreese Laboratory

Refreshments will be served


A high-quality, high-throughput, direct-growth approach to the integration of semiconductors on lattice-mismatched and amorphous substrates would revolutionize large-area and cost-sensitive technologies such as solar cells.  Here, we report the growth of high-quality Si and Ge on amorphous and lattice-mismatched materials using metal-catalyzed growth at the nano-scale.  This high-quality material is grown laterally over the substrate, either amorphous or crystalline, from a single seed ensuring that the material is single crystalline and has low dislocation densities determined by diffraction-contrast transmission electron microscopy.  The lateral growth of films and engineering of one nucleation site is enabled by the use of guided, selective, metal-catalyzed growth.  In this growth process, which is reminiscent of the Bridgman crystal growth process, it is likely important that the catalyst is a liquid at the growth temperature.  When growing Ge on Si, instead of nucleating dislocations from the surface, which is done in thin film growth, dislocations can form as the growth front moves laterally and accommodate the lattice mismatch.  In this manner, dislocations reside solely at the interface between the film and substrate extending from one end of the film to the other. We discuss our results at the nanoscale and describe a method to scale up this technology towards the wafer-scale and beyond.  Various applications are discussed including sensors and photovoltaics. Successful growth of high-quality, single-crystalline, semiconductor films on cheap, possibly amorphous, substrates would lead to the most efficient solar cells on cheap and large substrates and enable economies of scale.


In 2000, Nate Quitoriano received B.S. degrees in both Electrical Engineering and Computer Science and Materials Science and Engineering from the University of California, Berkeley.  As an undergraduate, he worked with Tim Sands on an establishing the kinetics of an ohmic, transient-liquid-phase bond for semiconductors. Nate received his Ph.D. in Materials Science Engineering in 2006 at MIT under the supervision of Gene Fitzgerald.  While at MIT, he worked on III-V, lattice-mismatched semiconductors and grew high-quality InP on GaAs using graded, compositional buffers to slowly increase the lattice constant. Following MIT, he worked in Stan William’s group at Hewlett-Packard Labs under Ted Kamins where he studied Si and Ge nanowires for use as sensors and electrical devices and successfully demonstrated Si nanotube resonators and guided Si nanowire growth.  Nate is now Assistant Professor of Materials Engineering at McGill University where his lab researches the growth of metal-catalyzed and liquid-phase epitaxial semiconductor growth as well as optical waveguide modeling.


MSE/IMR Special Seminar: The Toaster Project, Friday, September 7

A special seminar co-hosted by the Department of Materials Science and Engineering and the OSU Institute for Materials Research

The Toaster Project: A heroic attempt to build a simple electric appliance from scratch

Thomas Thwaites

Friday, September 7, 2012, 4:10 PM

100 Mendenhall Laboratory, 125 South Oval Mall

Reception with light refreshments to follow

Copies of Thwaites’ book The Toaster Project will be available for purchase



The Toaster Project chronicles Thomas Thwaites’ attempt to make an electric toaster from scratch – seeking iron, copper, mica, nickel and crude oil (for the plastic case) from disused mines and other sources around Britain, attempting to process these materials at home, and finally forming them into a version of a product that can be bought for only a few dollars.

This nine-month process to make a simple toaster is absurd, but perhaps so too is the massive industrial activity we pursue to achieve additional small comforts at ever lower prices.

The laboriousness of producing even the most basic material from the ground up exposes the fallacy in a return to some romantic ideal of a pre-industrialised time.

But at a moment in time when the effects of industry on the environment are no longer trivial even on a global scale, the throwaway toasters, and multitude of other small yet complex consumer appliances, have become absurd themselves.

The finished toaster cost £1187.54, and took nine months to make. It’s an electric appliance that disavows the infrastructure on which it relies. A convenient item that rejects the convenience of consumerism. A mass produced domestic product, ‘manufactured’ on a domestic scale. Its contradictions serve to highlight the amazing efficiencies of modern capitalism, but also to question our current trajectory.

Thomas Thwaites’ TED talk on The Toaster Project


Thomas Thwaites is a designer whose work examines how technology, science and economics interact with trends, fictions and beliefs, to shape our present society, and possible futures. As an undergraduate he studied economics and biology at University College London, and this training informs his design work. He completed his post-graduate masters degree in Design Interactions at the Royal College of Art in 2009.

His work is now exhibited internationally in galleries, at festivals and in museums including the National Museum of China and The Science Museum, London, attracting critical acclaim and a variety of awards. He has undertaken commissions and won several grants from organisations such as the Wellcome Trust and the UK Engineering and Physical Sciences Research Council.

His first book, The Toaster Project, is published by Princeton Architectural Press, and he has presented an accompanying four part television series for the UK national broadcaster Channel Four (for transmission in 2012). He is currently a fellow at Akademie Schloss Solitude, Stuttgart, Germany.

Self-Assembly in Materials Chemistry

Samuel I. Stupp

Departments of Chemistry, Materials Science and Engineering, and Medicine, Northwestern University

Wednesday, November 9, 2011

2:30 – 3:30 PM (light reception to follow)

E100 Scott Laboratory, 201 West 19th Avenue

Abstract: Self-assembly has emerged over the past two decades as a chemical strategy to create materials and devices. Based on lessons from biological systems, this strategy could be extraordinarily useful to craft highly functional materials from non-covalent assemblies of molecules and hybrid structures that imitate biomineralization. In order to harness the potential of the strategy in materials chemistry, the underlying science needed is a deep understanding of self-assembly codes based on both structure and external forces. So far self-assembly approaches have been developed mostly to organize molecules on surfaces, create supramolecular nanostructures with internal order, and to generate three dimensional patterns using phase separation of macromolecules. This lecture will illustrate self-assembly strategies to create more complex structures of interest in energy and medicine that have hierarchical order across scales. In these systems supramolecular self-assembly codes act synergistically with other forces to generate functional systems.
