A new paper on We previously reported that a dummy-SiO2 process improved the dielectric/GaN interface properties; however, the improvement mechanism has remained unclear. This study reveal that disordered GaN(O) polarity in the interfacial layer in a sample prepared by the standard process was restored to some extent after the dummy-SiO2 process, which likely led to the improved interface electrical properties has been published by IROKAWA, Yoshihiro et al.
