| Abstract: | Photosensitive EPR measurements ofS-state centers of gallium and tin in ZnTe single crystals are reported. In addition to large hyperfine interaction with the impurity nuclei the spectra show partially resolved superhyperfine structures arising from three shells of tellurium ligands. Both HF and SHF splittings decrease with increasing temperature. The samples exhibitp-type photoconductivity with the same spectral sensitivity observed with the generation and depletion of the EPR-spectrum. |
