The Semiconductor Epitaxy and Analysis Laboratory (SEAL) houses world-class facilities for research based on molecular beam epitaxy (MBE) and is Ohio State’s first and primary MBE facility. SEAL researchers are focused on MBE-grown III-V materials and devices, including both III-AsP and III-N compounds, and also III-V/Si integration and a variety of 2-D, 1-D and 0-D nanostructures. Research spans from basic physics, chemistry and interface science studies of technologically-relevant materials to device-driven epitaxy that supports major initiaatives in advanced photovoltaics, electronics, light emitters and detectors, and sensors. SEAL includes 5 MBE systems, 3 of which (for III-AsP and III-AsP/SiGe) are interlocked with an in-situ XPS analytic chamber, and 2 are dedicated for GaN and related materials. The Lab also includes a wide range of advanced, state of the art materials characterization tools to support advanced epitaxy and forefront advances in electronic materials. SEAL is a fully staffed user facility open to university and industry researchers.
