Abstract

Zn1−xMgxO films with wurtzite structure were electrochemically grown on the conductive glass substrates from a 0.1mol/L magnesium nitrate aqueous solution containing 0.001mol/L zinc Sulfate kept at 323K. With a decrease in the cathodic potential, Mg/(Zn+Mg) atomic ratios of Zn1−xMgxO films decreased and the lattice parameter for c axes decreased. The band gap energy of Zn1−xMgxO films increased with an increase of Mg/(Zn+Mg) atomic ratio. Thus, Mg/(Mg+Zn) atomic ratio and the bandgap energy of these Zn1−xMgxO films will be controlled by the cathodic potential.
