AbstractPositron lifetime technique and photoluminescence (PL) were employed to study the vacancy type defects in p-type Zn-doped and undoped GaSh samples. In the positron lifetime study, Ga vacancy related defect was identified in these materials and it was found to anneal out at temperature of about 350°C. For the PL measurement on the as-grown undoped sample performed at 10 K, a transition peak having a photon energy of about 777 meV was observed. This transition peak was observed to disappear after a 400°C annealing. Our results is consistent with the general belief that the 777 meV transition is related to the V GaGa sb defect, which is the proposed residual acceptor of GaSb.
