| Abstract: | Deep traps in Ga-doping ZnSe crystals have been investigated by DLTS and ODLTS methods. It is found that there is a donor trap at 0.17eV from the conduction band and two acceptor traps at 0.65eV and 0.72eV above the valencee band respectively.The donor trap at 0.l7eV is considered as one excitated state level of shallow donor gallfum. The acceptor trap at 0.65eV is the self-activated ( SA ) centre, which is identified as the associate between zinic vaccacy and shallow donor gallium. The 0.72eV acceptor trap is probably due to gallium at Se position heavy Ga-doping. |
