Show Abstract
It is deduced from the correlation among current‐voltage characteristics, photoconductivity spectra, and Fermi‐level energy that the current‐voltage characteristics of chromium‐doped semi‐insulating GaAs are dominated by the concentration ratio of the deep level related with chromium to the deep level related with oxygen. This correlation is explained by a space‐charge‐limited current model.
