RT Book, Section T1 Spatial distribution of vacancy defects in GaAs : Te wafers studied by positron annihilation A1 Cavallini, A. A1 Dupasquier, A. A1 Ferro, G. A1 Piqueras De Noriega, Francisco Javier A1 Valli, M. AB The radial vacancy distribution along a LEC-GaAs:Te wafer with an average free carrier concentration n = 1.5 x 10(18) cm(-3) was studied by means of positron lifetime spectroscopy. An M-shaped radial distribution of vacancy-like defects, most probably Te(As)V(Ga)(-), was observed.
