to the particulate and outgrowth during the PLD process. A good epitaxial growth on LaAlO3 (LAO) (100) substrates, however has been obtained for composition x = 0.9, 0.7 and0.5 with the heteroepitaxial relationship of (100)MgxZn1-xO∥(100)LAO (out-of-plane) and (011 ) MgxZn1-xO∥ (010)LAO (in-plane). These structural qualities suggest that cubic MgxZn1-xO alloys films have good potential in a variety......
