Bismuth telluride (Bi2Te3) nanowires: synthesis by cyclic electrodeposition/stripping, thinning by electrooxidation, and electrical power generation.
TL;DR: Nanowires composed of the thermoelectric material Bi2Te3 were synthesized on highly oriented pyrolytic graphite (HOPG) electrodes using the electrochemical step edge decoration (ESED) method and X-ray photoelectron spectroscopy (XPS) shows that these nanowires retain a Bi2 Te3 core but also have a thin surface layer composed of Bi and Te oxides.

X-ray Photoelectron Spectra and Electronic Structure of Bi2S3 Crystals
TL;DR: In this paper, the X-ray photoelectron spectra (XPS) of the valence band and core levels of the semiconductive Bi 2 S 3 single crystal, which shows anomalies in various physical properties and weak phase transitions without change of symmetry, were measured with monochromatized Al K a radiation in the energy range 0-1400 eV and the temperature range 160-460 K.

δ-Bi2O3 thin films prepared by reactive sputtering:Fabrication and characterization
TL;DR: In this paper, the influence of the oxygen flow ratio in the working gas and substrate temperature on the structures and phase components of the thin films were studied and the X-ray diffraction and transmission electron microscope analyses confirmed that the nanocrystalline nature of the δ-Bi2O3 thin films is responsible for the stabilization of high temperature phase in ambient temperature.

Electronegativity values from thermochemical data
TL;DR: In this paper, the electronegativities of sixtynine elements have been calculated from the most recent thermochemical data, and the mean deviation of the calculated electronegativity difference, 0·208 √ †, from the difference of the average electrone-gativities is 0·046 units.

Chemical bonding in bismuth telluride
J.R. Drabble,C.H.L. Goodman +1 more
TL;DR: In this paper, a model for the chemical bondins in bismuth telluride is proposed, which appears to dispose of some of the difficulties involved in earlier models, and is used to explain some properties of BTE and its alloys with BTE.
