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

Authors: F. Castro and B. Nabet

Affilation: Motorola Laboratories, United States

Pages: 454 - 457

Keywords: AlGaAs/GaAs heterointerface, non-uniform electric field, dielectric permmittivity, Franz-Keldysh, spatial modulation

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
