## Title

- title: Continuous real-time O 1s core XPS spectra of H2O adsorption on +c Ga-face
    and m-plane surfaces of GaN
  title_type: original
  lang: en

## Description

- description: The surface oxidation behavior of different GaN surfaces (the polar
    Ga-face (+c) and the nonpolar m-plane) under H2O vapor ambient 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.
    The O 1s core spectra were continuously obtained with about 30 s per scan at a
    binding energy of 538 to 525 eV. The first column of each scan is the binding
    energy, and the second column is the count rate. The data are in CSV and VAMAS
    formats. See the linked paper for experimental details.
