Abstract

Nonpolar a-plane ZnO film was successfully grown on (302)γ-LiAlO2 substrate by pulsed laser deposition. The temperature of substrate was 500℃, the film was pure nonpolar a-plane ZnO. The FWHM of the peak of near band emission in the PL spectrum was found to be only 115 meV. Both polarized transmission spectra and polarized Raman spectra revealed the in-plane anisotropy of the nonpolar ZnO film by the shift of absorption edge and the change of intensity of Raman E2 mode.

Abstract

Nonpolar a-plane (1120) ZnO films were successfully grown on (302) γ-LiAlO2 substrate by pulsed laser deposition. When the temperature of the substrate was 350℃, the film was mix-oriented(a and c) with a wide distribution of crystal grain size, and the c-plane ZnO was dominant. When the temperature of the substrate was 500℃, pure (1120) ZnO film was formed，with the FWHM of ZnO (1120) rocking curve ～0.65° and the grain size distribution narrowed. Its in-plane anisotropy was demonstrated by polarized transmission spectrum. The FWHM of the peak of near band emission in the PL spectra was found to be only 105meV for the sample with substrate temperature of 650℃，indicating the large size and uniform distribution of crystal grains which was also confirmed by AFM.
