Low-Resistivity p-Type Doping in Wurtzite ZnS Using Codoping Method

Abstract

By using first principles calculations, we propose a codoping method of using acceptors and donors simultaneously to realize low-resistivity and high carrier concentration p-type ZnS with wurtzite structure. The ionization energy of single NS can be lowered by introducing the IIIZn-NS (III = Al, Ga, In) passivation system. Codoping method in ZnS (2N, III) has lower formation energy comparing with single doping of N since III elements act as reactive codopants.
