## Title

- title: Continuous real-time O 1s core XPS spectra of initial O<sub>2</sub> molecule
    adsorption on polar and m-plane surfaces of GaN
  title_type: original
  lang: en

## Description

- description: The initial adsorption behavior of different GaN surfaces (the polar
    Ga-face (+c) and N-face (−c) and the nonpolar (101̅0) (m)-plane) under O<sub>2</sub>
    molecule beam irradiation was studied by continuous real-time monitoring of the
    O 1s core X-ray photoelectron spectra generated under synchrotron radiation. XPS
    measurements were performed at BL23SU, SPring-8. Analyzing the chemical shift
    allows for determining which site the oxygen atom bonds to depending on the polarity
    and plane of GaN, which contributes to detailed understanding of the surface oxidation
    process. The first column of each scan is the kinetic energy, and the second column
    is the count rate. Before starting XPS analysis, the sample was annealed at 900
    °C for 20 minutes. A scan was obtained every 30 seconds while irradiating the
    surface with O<sub>2</sub> molecule beam. The data are in CSV and VAMAS formats.
