Abstract

A method to fabricate monolithic broadband ultraviolet (UV) photodetectors with high tunable wavelength resolution was described using Mg xZn 1-xO composition-spread thin films. Structural changes in different regions of the spreads were investigated. An orientation relationship between (0001) oriented hexagonal (Zn,Mg)O and (100) oriented cubic (Mg,Zn)O was observed in the mixed region in the middle of the spread. The results show that this relationship can potentially be used to grow (100) oriented cubic structures.
