Paper Abstract

In the present paper we have shown the results of our DLTS studies in GaAs0.945Sb0.055 LPE semiconducting compound. Only one electron trap has been detected within whole experimental temperature range 80 K - 300 K. The concentration of the trap was found to be of the order of 1012 cm-3within the whole barrier region of the junction. The trap behaves very different from the usually observed traps in DLTS experiment. The DLTS peak is asymmetrically broadened and shifts to lower temperatures with increasing width of filling pulse which implies that dislocations are the origin of the trap.
