OverviewAI-generated summary

Steven Akwabli's research focuses on the development and characterization of germanium-tin (GeSn) avalanche photodiodes for infrared detection. His work investigates GeSn photodiodes with thick absorbers designed for short-wave infrared (SWIR) and extended SWIR detection, with some devices achieving cutoff wavelengths up to 2.7 micrometers. Akwabli also studies the role of alloy disorder scattering in high hole mobility GeSn quantum wells. He has published multiple papers on these topics, with recent work appearing in 2024 and 2026. His research collaborations at the University of Arkansas at Fayetteville include working with Justin Rudie, Perry C. Grant, Yanqing Qiu, and Quang Minh Thai, with whom he shares multiple publications.
