Survey and high-energy-resolution spectra are reported for MBE grown GaAs (001) that had been capped with As. The As cap was removed by heating in situ prior to analysis. The current data expands upon the spectral regions previously reported in Surface Science Spectra. High energy resolution spectral features reported include: 2p, 3s, 3p, 3d, and L3M4,5M4,5 peaks for As; 2p, 3s, 3p, 3d, and L3M4,5M4,5 peaks for Ga; and the valence band region.
Fe2O3-WO3 nanosystems synthesized by a hybrid CVD/sputtering route, and analyzed by X-ray photoelectron spectroscopy23(2016); http://dx.doi.org/10.1116/1.4964351View Description Hide Description
Fe2O3-WO3 nanosystems have been grown on metallic Ti substrates by a hybrid chemical vapor deposition (CVD) / Radio Frequency (RF)-sputtering route. The obtained specimens have been characterized in their structure, morphology and chemical composition by means of X-ray diffraction (XRD), field emission-scanning electron microscopy (FE-SEM), secondary ion mass spectrometry (SIMS) and X-ray photoelectron spectroscopy (XPS). Herein, a detailed XPS investigation of a representative sample is proposed. In addition to the wide scan spectrum, particular attention is dedicated to the analysis of O 1s, Fe 2p, W 4f, and W 4d core levels. The obtained results suggested the formation of pure Fe2O3-WO3 composites, in which each oxide maintained its chemical identity.
