摘要：

We use In species as reactive codopants for N acceptors to realize p-type ZnS. We find a change in the impurity states of N acceptors between ZnS:N and ZnS:(2N, In), based on the calculated results using ab initio electronic band structure calculations: while we find highly localized states of N acceptors for ZnS:N, we verify delocalized states for ZnS: (2N, In).
