PROBLEM TO BE SOLVED: To provide a doping method which is safe and easy, and is capable of obtaining p-type ZnO crystals excellent in controllability, regardless of the composition, conductivity type or the like of crystals to be doped.SOLUTION: A doping method includes the steps of: coating an aqueous solution of a diffusion agent of a compound containing a group I element as a constituent element on ZnO crystals to be fixed by drying; and subjecting the ZnO crystals including the diffusion agent fixed thereon to heat treatment and diffusing the group I element into the ZnO based crystals. |
