Abstract

Copper-doped Zinc Nitride (Cu:Zn3N2) films are grown on glass and Si substrates at various concentration of Cu (2.7, 4.9 and 5.7 at.%) by reactive RF magnetron co-sputtering. The impact of Cu atomic concentration on the structural and optoelectronic properties of Zn3N2 films is discussed in detail. Incorporation of Cu ions into Zn3N2 host lattice is confirmed by EDAX analysis. Hall Effect results indicate that the fabricated film exhibited p-type conductivity with high hole concentration of 1.78–1.36 × 1018 cm−3, resistivity of 0.48–0.56 Ω cm, and high hole mobility of ~8 cm2 V−1 s−1. The transmittance of Cu:Zn3N2 films are found to be in the range of 11–18% at the wavelength of 500 nm and hence the band gap decreases from 1.80 to 1.61 eV when Cu doping content is increased. These findings would assist Cu:Zn3N2 as a potential candidate for p-type layer in thin film solar cells.
