Chalcogens and Metal Chalcogenides
2010It is common that the three heaviest elements of the sulfur sub-group, namely selenium, tellurium, and polonium, be collectively referred to as the “chalcogens,” and the term chalcogen be addressed only for these elements – in practice, only for the chemically and technologically important selenium and tellurium; however, according to the official ...

Doping in metal chalcogenide glasses
Semiconductors, 1998Chalcogenide glasses that contain sufficient concentrations of metal atoms can be p-type doped. This doping results in part because the local structural order is tetrahedral at the metal and the chalcogen sites in these glasses. At concentrations exceeding 1019 cm−3, oxygen promotes doping by increasing the densities of dangling-bond defects at ...

A novel metal chalcogenide: HgCd4S5
Russian Journal of Inorganic Chemistry, 2011A novel metal chalcogenide HgCd4S5 (1) was synthesized from solid-state reactions and structurally characterized. Compound 1 crystallizes in the space group C2221 of the orthorhombic system with four formula units in a cell: a = 12.5661(5) A, b = 7.2551(5) A, c = 10.7520(7) A, V = 980.2(1) A3, Cd4HgS5, M r

Chemistry of Chalcogenides and Transition Metals
2016The lone-pair electrons of chalcogen atoms and the presence of d-orbitals of transition metal atoms determine the rich chemistry of transition-metal dichalcogenides. This Chapter presents a brief overview of the fundamental concepts that are needed to understand the chemistry of these materials.

Photodoping of amorphous chalcogenides by metals
Advances in Physics, 1991Abstract The present paper reviews the results of experimental investigations of the photodoping of amorphous chalcogenides by metals, and in particular by silver. The kinetics of the photodissolution of the metal are described as also is the influence on the photodissolution rate of such factors as the wavelength and intensity of light, the ...

The occurrence of alkali metal intercalated compounds from layered chalcogenides with two dimensional structures was reported for the first time in 1965 by Rudorff [1]. Rapidly this field of research proved very fruitful. A first exhaustive study in the more general framework of ternary chalcogenides with alkali and transition metals has been given in ...
