Abstract
The photoelectrochemical properties of epitaxial films on sapphire (0001) substrates have been investigated. The flatband potential of is shifted to more positive voltages with increasing indium incorporation. In aqueous HBr solution, the turnover number of the electrode reaches 847 after illumination, which suggests that has good photostability. Moreover, shows highest visible-light response among and the incident photon conversion efficiency is about 9% at in the HBr solution.
