Abstract
Measurements of the temperature dependence of electrical resistivity in - and -type cobalt-doped germanium crystals indicate that cobalt introduces acceptor levels in germanium at 0.31±0.01 ev from the conduction band and 0.25±0.01 ev from the valence band. Ionization energies deduced from infrared photoconductivity studies at 77°K are in good agreement with the values obtained from resistivity measurements. -type samples show higher intrinsic photosensitivity than -type samples and demonstrate quenching effects.
