Abstract(in English) A ~6.2 nm-thick SiO2 was deposited on n-type GaN(0001) by the remote O2 plasma enhanced CVD, and chemical bonding features and filled defect states of SiO2/GaN structure were studied by x-ray photoelectron spectroscopy (XPS) and total photoelectron yield spectroscopy (PYS), respectively. And, post deposition anneal (PDA) was performed in XPS/PYS system without air exposure to evaluate the thermal stability of SiO2/GaN structure. Chemical structure at SiO2/GaN interface was found to be thermally stable against PDA at temperatures up to 600C. With increasing PDA temperatures over 700C, diffusion and incorporation of Ga atoms into SiO2 were detected. And, it was found that PDA at temperatures over 600C was effective to decrease the filled gap states in the region near the SiO2/GaN interface.
