“…Therefore, many attempts have been tried using alternative substrates with smaller anisotropic lattice mismatch to deposit non-polar ZnO. The growth of a-plane ZnO films was achieved on (3 0 2) g-LiAlO 2 , (0 1 0) LiGaO 3 , (0 0 1) SrTiO 3 , and (0 0 1) LaAlO 3 (LAO) substrates [7][8][9][10]. For the deposition of m-plane ZnO, ð1010Þsapphire, (0 0 1) MgO and (1 0 0) g-LiAlO 2 substrates were also successfully demonstrated in previous reports [11][12][13].…”
