Abstract
A relationship between the electrical activation of Si in ion-implanted In₀.₅₃Ga₀.₄₇As and material microstructure after ion implantation is demonstrated. By altering specimen temperature during ion implantation to control material microstructure, it is advanced that increasing sub-amorphizing damage (point defects) from Si+ implantation results in enhanced electrical activation of Si in In₀.₅₃Ga₀.₄₇As by providing a greater number of possible sites for substitutional incorporation of Si into the crystal lattice upon subsequent annealing.
