Biography and Research Information

OverviewAI-generated summary

Sylvester Amoah's research focuses on the development and characterization of semiconductor materials and devices, particularly those based on germanium and tin alloys for photonic applications. His work investigates the growth of pseudomorphic GeSn layers, including compositions up to 16.7% Sn, using molecular beam epitaxy (MBE) at low pressures. He has explored the integration of these materials onto silicon photonics platforms, aiming for applications in integrated circuits and infrared detection. His publications include studies on electrically injected GeSn lasers emitting at wavelengths up to 2.7 μm and the development of monolithic Germanium–Tin on Si Avalanche Photodiodes. Amoah also examines the fundamental properties of these materials, such as the role of dislocations on Sn diffusion during annealing and the growth of single crystalline Ge thin films on sapphire substrates. He has a h-index of 7 and 391 total citations across 25 publications.
