WebNov 9, 2012 · The stability of the Ga interstitials is further increased at surfaces. The present results suggest that the energetically favorable Ga interstitial atoms are much more abundant in GaAsN than the previously considered N defects, which have relatively large formation energies. WebGaAs is a direct band gap semiconductor,which means that the minimum of the conduction band is directly over the maximum of the valance band.For that reason …
