Recent progress in research on MgxZn1–xO alloys

Ternary MgxZn1–xO alloys are attracting considerable attention for possible application in optoelectronic devices. Recently, a great deal of research on MgxZn1–xO have been reported by many groups, such as growth and optical properties, phase evolution from hexagonal-phase to cubic-phase with the increase of the Mg concentration, thermal stability of MgxZn1–xO films and heterointerfaces, fabrication of excellent ZnO/MgxZn1–xO heterostructure, quantum well or superlattice and application of MgxZn1–xO material in optoelectronic devices. In this paper, we summarize the recent progress in MgxZn1–xO and the advance in device fabrication.
