The bipolar doping of ZnS via native defects and external dopants

The first-principle total-energy calculations are employed to perform a systematic studies on the dopability of both n- and p-type ZnS compared to that of ZnO. The results suggested that native n-type doping of ZnS with dpants is harder to achieve than in ZnO due to the readiness of forming native compensating centers and higher ionization energy of donors in ZnS.
