Superconductivity in transition metal chalcogenides

Physica B+C, 1981
Abstract The upper critical field anisotropy H C2‖ H C2⊥ has been studied in 2H-TaS2 intercalated with methylamine and pyridine, and comparison to theoretical models predicting dimensional crossover has been made. The temperature dependence of HC2‖ shows upward curvature over a substantial range of temperature below Tc, and good ...

Synthesis and Applications of Nanostructured Hollow Transition Metal Chalcogenides

Small, 2021
AbstractNanostructures with well‐defined structures and rich active sites occupy an important position for efficient energy storage and conversion. Recent studies have shown that a transition metal chalcogenide (TMC) has a unique structure, such as diverse structural morphology, excellent stability, high efficiency, etc., and is used in the fields of ...

Atomic Engineering of Chalcogenide Layer in Transition Metal Chalcogenides

ECS Meeting Abstracts, 2017
Atomically thin transition metal chalcogenides (TMDs), members of two-dimensional (2D) material family, have received great attention due to their novel optoelectronic and electronic properties. CVD technique have been well developed to synthesize monolayer TMDs, such as MoS2, WS2, WSe2, and MoSe2 where transition metals are sandwiched by the same ...

A Synthetic Method for Transition‐Metal Chalcogenide Nanocrystals

Chemistry – A European Journal, 2009
AbstractA facile wet route was applied to prepare a series of chalcogenide semiconductor nanocrystals (see figure) in controllable shapes and sizes, while a general bottom‐up approach was adopted to transform these cyclohexane‐soluble monodisperse nanocrystals into water‐soluble colloidal spheres.magnified imageIn this paper, we prepared a series of ...

Phase transitions in transition-metal chalcogenides

Solid State Communications, 1966
Abstract In many transition metal chalcogenides the anions are hexagonally close packed, the cations occupying octahedral sites. In compounds of the composition M 1−x X (M=metal, X=chalcogene) the octahedral sites are partly vacant. If the vacant sites are distributed randomly over all octahedral sites, the crystal has the full symmetry of the NiAs ...

Chemistry of Chalcogenides and Transition Metals

2016
The 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.

Magnetism and Superconductivity of Transition Metal Chalcogenides

Physics of Metals and Metallography, 2018
The structural, superconducting, and magnetic properties of transition metal (M) chalcogenides with layered crystal structures are considered depending on the metal-to-chalcogen (M: X) ratio. The main attention is paid to iron containing chalcogenides, in particular, to the Fe-intercalated titanium dichalcogenides FeyTiX2 and (Fe,M)7X8 compounds with ...
