Despite nearly identical ion-energy loss in these materials, their behavior under swift-heavy-ion irradiation is strikingly different: InP and Ga0.50 In0.50 P are readily amorphized, GaP and GaAs remain almost undamaged and InAs and Ga0.47 In0.53 As exhibit intermediate behavior. A material-dependent combination of irradiation-induced damage formation and annealing is proposed to describe the different responses of the III-V materials to electronic energy loss.201010.1103/PhysRevB.81.0752012015-12-08
