Journal ArticleDOI
Effects of electron confinement on thermionic emission current in a modulation doped heterostructure
TL;DR: In this paper, the authors discuss mechanisms responsible for the reduction of electron thermionic emission current from a Schottky contact to a modulation doped semiconductor compared to a bulk semiconductor.
Journal ArticleDOI
Intermediate temperature grown GaAs/AlGaAs photodetector with low dark current and high sensitivity
TL;DR: A photodetector in which Schottky metal laterally contacts the molecular beam epitaxy grown heterointerface of intermediate-temperature GaAs and Al0.24Ga0.76As is reported in this article.
Journal ArticleDOI
Accurate closed-form expression for sheet carrier density calculations in modulation-doped heterostructures
TL;DR: In this paper, an accurate expression for sheet carrier density (n/sub s/) calculations in modulation-doped heterostructures is developed from a nonlinear model of the Fermi potential variation with n/ sub s.
Proceedings ArticleDOI
A large area, high speed photodetector for a microwave modulated hybrid lidar-radar application
TL;DR: In this article, a vacuum photodiode that employs a planar 300 /spl mu/m/sup 2/ metal-semiconductor-metal device as the anode to increase the response speed is presented.
Journal ArticleDOI
