Abstract
Damage accumulation and amorphization in GaAs(100) by MeV Si+ ion impl antation at different tilt angles have been studied using the Rutherfo rd backscattering and channeling technique. It was found that the tota l amount of damage increases linearly with the implant dose at doses l ess than the threshold dose for amorphization. Layer by layer amorphiz ation was observed at doses higher than the, threshold dose. The damag e distribution is strongly influenced by the target tilt angle. With a n increase in the implant tilt angle, the damage level decreases. A mo del for the damage accumulation and amorphization is discussed.
