Abstract

The regrowing features of disordered germanium under low power multi-pulse irradiation are discussed. It is shown that implanted amorphous germanium starts the regrowth from the specimen surface while glow-discharge amorphous material starts from the amorphous-single crystal interface. Evidence against a melting mechanism in the case of multi-pulse irradiation are also presented.
