Witryna1 cze 2010 · According to recent theoretical calculations, Al is considered to be a shallow donor impurity locating at 0.12 eV below the conduction band edge of bulk ZnO [19]. Zn vacancy (the intrinsic defects of ZnO) is considered to be a deep acceptor located at 2.5 eV below the conduction edge of ZnO [10]. Witryna4 wrz 1998 · In this paper, we studied the feasibility of using a commercial etch chamber to perform plasma doping to form shallow p + -n junction. The plasma doping has the advantage of high wafer throughput compared to conventional low energy implanters. Ultra-shallow boron implantation was done in a plasma reactor with a Helicon plasma …
