An unconventional non-polar (12 3 ¯ 0)ZnO epitaxial film is grown on (118)LaAlO3(LAO) substrate by pulsed laser deposition. X-ray diffraction pole figures and transmission electron microscopy show that the crystal orientation relationships between non-polar (123̄0)ZnO and (118)LAO substrate are (0001)ZnO // (1̄10)LAO and (112̄0)ZnO // (001)LAO. The Raman spectrum with a significant E2 peaked at 439 cm − 1 clearly indicates the formation of non-polar ZnO film. Photoluminescence measurement of the non-polar ZnO film shows a strong near-band-edge emission located at 3.3 eV with negligible green-yellow emission. [ABSTRACT FROM AUTHOR]
