“…However, until now, the issue in achieving highly p‐type doped ZnO is still a challenge. Normally p‐type ZnO are achieved by doping with single elements such as P, N, As, Li, Sb, Ag, Al, Mg, and Co . Thus, the electrical and optical properties of single elements doped p‐type ZnO films are also determined by dopants and defect complexes, which introduced through synthesis techniques.…”
