We have demonstrated for the first time abrupt and shallow p-type layers in GaAs by implanting mercury and the use of rapid thermal annealing (RTA). We have observed that the time dependence of electrical activation characteristics of the Hg-implanted samples is similar to other p-type species. Furthermore, abrupt electrical profiles with hole concentrations of the order of 9×1018cm−3 have been achieved after annealing at 900°C for 3 s.
