Atomic Engineering of Chalcogenide Layer in Transition Metal Chalcogenides
ECS Meeting Abstracts, 2017Atomically 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 ...

CVD of metal chalcogenide films
Le Journal de Physique IV, 1999The preparation of SnE, Ag 2 E and Cu 2 E (E = Se, Te) thin films by Chemical Vapor Deposition (CVD) and Vapor Phase Transport (VPT) has been studied. The precursors, [Sn{(SiMe 3 ) 2 CH} 2 (μ-E)] 2 (E = Te, Se), have been studied for the deposition of SnE films.

Geometrical structure and metal-metal bonding in niobium chalcogenides and chalcogenide halides
Journal of Physics C: Solid State Physics, 1980An atomic orbital study is presented for the electronic structure of NbS2Cl2, NbSe2Cl2, Nb3Se5Cl7, Nb2Se9 and I0.33NbSe4. Each crystal structure is built up from Nb2X4 clusters (X=S,Se) containing a strong metal-metal bond. Band structures and densities of states are displayed and interpreted in terms of the different geometrical arrangements of the ...

Cluster Transition Metal Chalcogenide Halides
Russian Chemical Reviews, 1985The literature data on cluster transition metal chalcogenide halides are described systematically and discussed. The structures of these compounds are examined and compared with those of the analogous cluster metal halides and chalcogenides. The principal preparative methods of synthesis of the cluster chalcogenide halides are discussed and a ...

Superconductivity in transition metal chalcogenides
Physica B+C, 1981Abstract 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 ...

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 ...

Transition-metal-doped chalcogenide lasers
Journal of Electronic Materials, 2002Broadly tunable mid-infrared lasers are desirable for a number of scientific, remote-sensing, and military applications. Recently, Cr2+-doped chalcogenide lasers have emerged as an attractive source of tunable laser radiation in the 2-3.4-µm region. This paper provides a brief introduction to this field, summarizes key laser work to date, and provides ...
