Damage production in GaAs by H+ irradiation

Abstract
Rutherford backscattering and proton induced x-ray emission in combination with channeling have been used to study damage production in GaAs by proton irradiation. The average cross section for displacement of Ga and As atoms has been determined and found to agree well with the cross section calculated from the elastic displacement theory of Kinchin and Pease. In addition, we have demonstrated that about 6% more Ga atoms are displaced than As atoms.
