Description

Ternary semiconductors of type □AIIB2IIIC4VI with an ordered array of vacancies were investigated by PAC. Thereby the six probes 111Cd, 117Cd(117In), 111In(111Cd), 111Ag(111Cd), 77Br(77Se) and 77Kr(77Br) were applied. The positions of the different probes are determined and the corresponding electric field gradients by the WIEN 95 code calculated. By 111Ag(111Cd)-probes the vacancies could be substituted. The electronic charge density distributions are discussed. At elevated temperatures the substances show order-disorder transitions. As compared to the X-ray diffraction patterns the beginning of disorder is observed by PAC at distinctly lower temperatures
