Description

Data on the effects of 140 keV Zn+ implantation of (100)GaAs and the consequent low-power pulsed laser annealing (LPPLA) on the composition of the surface layers are presented. The implantation dose was 1014 cm-2 and the sample temperature was kept at 110 ± 10oC. The LPPLA was carried out by 10-30 pulses of a Q-switched ruby laser equipped with a spatial homogenizer. The crystal surface was studied by XPS analysis combined with depth profiling with the use of 1 keV Ar+. The results presented include the depth redistribution of oxygen and the As/Ga ratio as well as the oxide thickness for (a) virgin, (b) as-implanted and (c) implanted and then annealed samples.
