摘要：

Vanadium doped CdTe is studied by electron paramagnetic resonance (EPR), photo-EPR, and optical absorption. The EPR measurements identify vanadium substitutional for Cd in the oxidation states V2+ and V3+. Whereas V3+ shows the well-known isotropic EPR spectrum, the V2+ spectrum features triclinic symmetry due to a strong Jahn-Teller coupling. By photo-EPR, the V2+/V3+-donor level was determined at 0.67 eV below the conduction band. In absorption, additionally to internal crystal field transitions of vanadium, we also observe the recharging process V3+ to V2+.
