Evidence of lower than three valence of bismuth in Bi2Sr2Ca1Cu2O8 superconductor
TL;DR: In this paper, a superconducting single-phase Bi 2 Sr 2 Ca 1 Cu 2 O 8 has been investigated using X-ray photoelectron spectroscopy and the binding energy of 158.3 eV for the Bi 4f 7 2 level indicates the presence of bismuth in a valency state lower than + 3.

Thiol-Free Synthesis of Bright Near-Infrared-Emitting Ag2S Nanocrystals through Heterovalent-Metal Decoration for Ecofriendly Solar Cells
TL;DR: In this article , a general strategy of surface heterovalent-metal (Bi3+, Ga3+, In3+, Sb3+, and Zn2+) decoration was developed to synthesize colloidal cation-rich Ag2S nanocrystals achieving a high photoluminescence quantum yield up to 22% at ∼1230 nm.

Photoemission study of the BiCuO interface
T. Conard,Robert Sporken,Jacques Ghijsen,L.-M. Yu,Roland Caudano,R. Seemann,Robert L. Johnson +6 more
TL;DR: In this article, the formation of the BiCuO interface was studied by photoelectron spectroscopy using synchrotron radiation in the VUV range, where a thin copper layer was placed onto a SrTiO3(100) substrate and oxidising it with atomic oxygen to form CuO.

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.

H J Goldsmid,R W Douglas +1 more
TL;DR: In this article, the authors proposed that semiconductors should be chosen with high mean atomic weights and that they should be prepared with thermoelectric powers lying between 200 and 300 μVC-1.

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.
