Abstract


Effect of 100 MeV 197Au implantation, followed by Rapid Thermal Annealing on electrical and optical characteristic is reported. Single crystal n+ GaAs substrates of orientation have been implanted at room temperature with 197Au ions to the doses of 1X1012, 1X1013, 1X1014 ions/cm2. The as-implanted current-voltage (I-V) characteristic of samples is studied and the optical investigations in IR and mid IR-range have been made. The implanted samples were isochronally annealed by RTA system at different temperatures and the room temperature electrical characterization and the optical investigations are reported.

Keywords
