Injection-enhanced defect reactions in III-V light emitting diodes

Abstract

Injection-enhanced defect transformations in GaP LEDs with active layer doped by N (GaP:N), or N, Zn, and O (GaP:N,ZnO), as well as AlGaAs:Zn, AlGaAs:Ge, and GaAs:Si LEDs were investigated both theoretically and experimentally. Four principal types of defect transformations were determined to take place in these LEDs. Their nature and parameters were determined from the comparison of theoretical and experimental data.<>
