Abstract

The geometric structure, band structure and density of state of pure and Ag-N, Ag-2N codoped wurtzite ZnO have been investigated by first-principles ultrasoft pseudopotential method in the generalized gradient approximation. These structures induce fully occupied defect states above the valence-band maximum of bulk ZnO. The calculation results show that the codoped structure Ag-N has better stability. Meanwhile, the carrier concentration is increased in the Ag-2N codoped configuration where the delocalized features are obvious. Our findings suggest that codoping of Ag-2N could efficiently enhance the N dopant solubility and is likely to yield better p-type conductivity.
