Abstract: | Using the time differential perturbed angular correlation technique (TDPAC), the electric hyperfine interaction of111Cd in the II-VI-semiconductor CdS was investigated. The results of the temperature and pressure dependence of the electric field gradient (EFG) are discussed. The binding energyE
b for111In at a Cd lattice site and a Cd vacancy (111InCd–VCd–pair) could be estimated to 340 meV±80 meV by means of an Arrhenius-Plot. The disappearance of the 79 MHz and 73 MHz frequencies under a pressure of about 30 kbar could be due to their vacancy character or to the beginning of the phase transition to rocksalt structure. |
