TL;DR: In this paper, the effect of thermal annealing on the structural, chemical, electrical, and optical properties of Ga-doped ZnO (GZO) films was investigated in various ambients, such as oxygen, nitrogen, and forming gas (95% N 2 5% H 2 ).

TL;DR: In this article, high energy resolution photoelectron spectroscopy with synchrotron radiation was used to study the chemisorption of O atoms on graphite and the thermal reduction of the oxidized surface.
Abstract: The chemisorption of O atoms on graphite and the thermal reduction of the oxidized surface were studied by means of high energy resolution photoelectron spectroscopy with synchrotron radiation. The C 1s and O 1s core levels and the valence band spectra were used to identify the different oxidizing surface species and to evaluate the extension of the sp2 conjugation as a function of oxidation time and annealing temperature. We found that epoxy groups are the dominant species only at the low oxidation stage, and ethers and semiquinones form as oxidation proceeds. The evolution of the ether/epoxy ratio with increasing oxygen coverage provides evidence for the occurrence of C–C bond unzipping. Epoxy groups are the functionalities with the lowest thermal stability and start to desorb around 370 K, strongly affecting the desorption temperature of other functional groups. The ratio between ethers and epoxy groups determines the balance between epoxy–epoxy and epoxy–ether reactions, the latter promoting the remov...

TL;DR: In this paper, the role of surface moisture in capturing Hg0 was examined using X-ray absorption fine structure (XAFS) spectroscopy and the results indicated that surface oxygen complexes provide the active sites for mercury bonding.
