PALLADIUM AS IMPURITY IN ZNTE

In the II-VI compound ZnTe perturbed angular correlation and tracer di ffusion experiments with the nuclear probe Pd-100/Rh-100 revealed the formation of a defect complex by the observation of a well-defined qua drupole interaction in tellurium-rich crystals. The defect complex is tentatively interpreted as a Pd A-centre with Pd on the chalcogen latt ice site. Using the DLTS method no deep levels correlated to implanted palladium could be detected in the range of 0.2 to 0.8 eV above the v alence band edge.
