TL;DR: In this paper, the thermal and chemical stability of perfluoropentacene (PFP) thin films grown by organic molecular beam deposition onto the (111)-oriented surfaces of the coinage metals copper, silver, and gold have been studied by means of temperature dependent X-ray photoelectron spectroscopy (XPS) and Near-Edge Xray absorption fine structure spectroscope (NEXAFS).

TL;DR: To fully exploit the information contained in the spectra gained by the high-energy-resolution technique, (time-dependent) density functional theory calculations based on plane-wave and localized orbital basis sets are performed, which in combination allow the complete spectral range from the prepeak to the first resonances above the edge step to be covered.

TL;DR: In this article, the atomic and electronic structure and the formation energy of the Ga-rich GaAs(001)-β2(4 x 2) surface is compared with recent results for the As-rich As-As (001)-(2 x 4) surface reconstructions.

TL;DR: In this paper, the authors present an atomic simulation on the silicon carbide precipitation in bulk silicon employing both, classical potential and first-principles methods, aiming at a comprehensive, microscopic understanding of the precipitation mechanism in the context of controversial discussions.
