Non-polar m-plane ZnO thin film has been prepared on γ-LiAlO2(1 0 0)substrate via the low pressure metal organic chemical vapor deposition. Obvious intensity variation of the E2 mode in the polarized Raman spectra and the absorption edge shift in the polarized optical transmission spectra indicate that the m-plane film exhibits optical anisotropy, which have applications in certain optical devices, such as the UV modulator and polarization-dependent beam switch. From the atomic force microscopy images, highly-oriented uniform-sized grains of rectangular shape were observed.
