Single wurtzite p-type Zn{sub 1-y}Cu{sub y}O{sub 1-x}S{sub x} alloy films with 0.081{<=}x{<=}0.186 and 0.09{<=}y{<=}0.159 were grown on quartz reproducibly by magnetron sputtering. The alloys show very stable p-type conductivity with a hole concentration of 4.31-5.78x10{sup 19} cm{sup -3}, a resistivity of 0.29-0.34 {Omega} cm and a mobility of 0.32-0.49 cm{sup 2} V{sup -1} s{sup -1}. The p-type conductivity is attributed to substitution of Cu{sup +1} for the Zn site, and the ionization energy of the Cu{sup +1} acceptor is measured to be 53 meV, much less than that of Cu-doped ZnO reported previously. The small ionization energy is due to Cu heavy doping and increase in valence band maximum of ZnO induced by alloying with S.
