Abstract :
A Q-switched ruby laser has been used to anneal GaAs implanted with selenium or tellurium ions. Electron concentrations in the range 1¿2 à 1019 cm¿3 were measured for samples implanted at room temperature or 200°C with a dose of 1¿5 à 1015 ions cm¿2. High electrical activities were obtained both with and without Si3N4 coatings.
