摘 要:In this paper,we report the growth of Ga As Sb and its crystalline property under various Sb2/As2 flux ratios and growth *** simulated the incorporation difference between Sb2 and As2 by using a non-equilibrium thermodynamic *** study of Ga As Sb growth has successfully yielded,high quality In Ga As/Ga As Sb Type II superlattice for which the optical properties were characterized by photoluminescence at different excitation power and temperature.A blue-shift in luminescence peak energy with excitation power was observed and was described by a non-equilibrium carrier density *** measured and analyzed the dependences of peak energy and integrated intensity on *** thermal processes were observed from intensity dependent photoluminescence measurements.
