Spatial Modulation of the Dielectric Permittivity and its Effect on the Spectral Responsivity of Heterodimensional Photodetectors

, ,

Keywords: , , , ,

Spectral photocurrent measurements on AlGaAs/GaAs heterodimensional detectors show a peak near the absorption edge of GaAs under low incident power and at high biasing levels. Previous work has attributed similar results to the Franz-Keldysh spectral mod
