It has been reported that one of the reasons of carrier overflow is polarization charges induced at hetero interfaces. In this study, we investigate influences of the polarization charges on the carrier transport and a method to compensate the positive polarization charges induced at the GaN barrier/AlGaN electron blocking layer interface in order to suppress the influences. The simulation results revealed that the positive polarization charges in the p-layers were compensated only by the ionized acceptors. We then propose heavy doping with Mg acceptor to the interface induced the positive polarization charges in order for compensating the positive charges. The simulation results indicate that the method is effective to reduce operating voltages and improve injection efficiency. The fabricated blue LED with the heavy Mg doping at the barrier/electron blocking layer interface showed a reduction of the operating voltage. |
