OverviewAI-generated summary
Solomon Ojo's research focuses on the development and characterization of germanium-tin (GeSn) semiconductor materials for optoelectronic applications, particularly in the mid-infrared spectrum. His work has involved the growth of pseudomorphic GeSn layers with controlled tin compositions using molecular beam epitaxy, achieving significant Sn concentrations up to 16.7% at low pressures. Ojo has contributed to the advancement of electrically injected GeSn lasers on silicon platforms, with recent publications reporting peak wavelengths extending to 2.7 μm and operation at 140 K. His research also investigates GeSn/SiGeSn quantum wells for integrated photonics circuits and explores the optical and structural properties of these heterostructures. Ojo has a publication record of 39 papers with 611 citations and an h-index of 10. He has collaborated extensively with Shui-Qing Yu, Hryhorii Stanchu, Wei Du, and Sudip Acharya at the University of Arkansas at Fayetteville.
