Biography and Research Information

OverviewAI-generated summary

Joshua M. Grant is a faculty member at the University of Arkansas at Fayetteville whose research focuses on the development and study of germanium-tin (GeSn) semiconductor materials for mid-infrared applications. His work involves the growth of pseudomorphic GeSn on silicon substrates, often utilizing aspect ratio trapping techniques to achieve high tin compositions and specific material properties. Grant investigates the optical and electrical characteristics of GeSn quantum wells and lasers, exploring their potential for integrated photonics circuits and midwave infrared device applications. His recent publications include studies on electrically injected GeSn lasers with wavelengths up to 2.7 μm, enhanced carrier collection efficiency in GeSn single quantum wells, and the development of GeSn growth for midwave infrared applications. He has a substantial publication record and collaborates with several colleagues at the University of Arkansas, including Wei Du, Solomon Ojo, Shui-Qing Yu, and Hryhorii Stanchu.
