Abstract

Using density functional theory (DFT) we report results for the electronic structure and vibrational dynamics of hydrogenated �� reconstructed Silicon Carbide (001) (3x2) surfaces with various levels of hydrogenation. These results were obtained using density functional theory with a generalized gradient exchange correlation function. The calculations reveal that metallization can be achieved via hydrogen atoms occupying the second silicon layer. Further increases of hydrogen occupation on the second silicon layer sites result in a loss of this metallization. For the former scenario, where metallization occurs, we found a new vibrational mode at 1870 cm-1, which is distinct from the mode associated with hydrogen atoms on the first layer. Furthermore, we found the diffusion barrier for a hydrogen atom to move from the second to the third silicon layer to be 258 meV.

81. Phase transition and thermal stability of epitaxial PtSe 2 nanolayer on Pt(111).

Author

Abstract

This work relates to direct synthesis of the two-dimensional (2D) transition metal dichalchogenide (TMD) PtSe 2 using an original method based on chemical deposition during immersion of a Pt(111) surface into aqueous Na 2 Se solution. Annealing of the sample induces significant modifications in the structural and electronic properties of the resulting PtSe 2 film. We report systematic investigations of temperature dependent phase transitions by combining synchrotron based high-resolution X-ray photoemission (XPS), low temperature scanning tunnelling microscopy (LT-STM) and low energy electron diffraction (LEED). From the STM images, a phase transition from TMD 2H-PtSe 2 to Pt 2 Se alloy monolayer structure is observed, in agreement with the LEED patterns showing a transition from (4 × 4) to (√3 × √3)R30° and then to a (2 × 2) superstructure. This progressive evolution of the surface reconstruction has been monitored by XPS through systematic de-convolution of the Pt4f and Se3d core level peaks at different temperatures. The present work provides an alternative method for the large scale fabrication of 2D transition metal dichalchogenide films., Competing Interests: The authors declare no conflicts of interest., (This journal is © The Royal Society of Chemistry.)

82. Burning match oxidation process of silicon nanowires screened at the atomic scale.

Author

De Padova P, Leandri C, Vizzini S, Quaresima C, Perfetti P, Olivieri B, Oughaddou H, Aufray B, and Le Lay G

Abstract

Silicon oxide nanowires hold great promise for functional nanoscale electronics. Here, we investigate the oxidation of straight, massively parallel, metallic Si nanowires. We show that the oxidation process starts at the Si NW terminations and develops like a burning match. While the spectroscopic signatures on the virgin, metallic part, are unaltered we identify four new oxidation states on the oxidized part, which show a gap opening, thus revealing the formation of a transverse internal nanojunction.
