Title:Electrochemistry of Gallium Arsenide
Author(s):Benard, David James
Department / Program:Physics
Subject(s):gallium arsenide
Abstract:The gallium arsenide electrode was investigated with respect to its electrochemical behavior in a sulfuric acid electrolyte. The differential capacity and luminescence of the electrode were measured in addition to the usual steady state currents and photoeffects. It was found that the electrochemical behavior was dissimilar to the case of germanium where the surface states could be neglected. At gallium arsenide the surface states were found to be responsible for a stabilization of the space charge barrier height as well as fast recombination and generation effects. The reduction of hydrogen was found to inject holes rather than extract electrons. The traditional tests for the reaction mechanism based on photoeffects were found inadequate as it is shown that similar results will be obtained if either the conduction or valence bands carry the reaction current.
