The depletion widths used in the calculation are much smaller than the fully developed macroscopic value. This is to account for the fact that the triangular barrier assumption in the model overes ...

Fabrication and Characterization of a CdS Photoconductor
... CdS is a highly resistive material in its pure form, due to its bandgap of 2.5 eV. This means that not many valence band electrons are excited into the conduction bands at room temperature (kT = 0.026 eV << Eg.). If illuminated, however, electrons may be promoted to the conduction band as was found ...
