Excitons in monolayer transition metal dichalcogenides

Journal of Physics: Condensed Matter, 2015
We theoretically investigate the exciton formed with two massive Dirac particles in monolayer [Formula: see text] and other transition metal dichalcogenides as well as two layers separated by a dielectric layer. In the low-energy limit, the separation of the center-of-mass and relative motions is obtained.

Selective Chemical Response of Transition Metal Dichalcogenides and Metal Dichalcogenides in Ambient Conditions

ACS Applied Materials & Interfaces, 2017
To fabricate practical devices based on semiconducting two-dimensional (2D) materials, the source, channel, and drain materials are exposed to ambient air. However, the response of layered 2D materials to air has not been fully elucidated at the molecular level. In the present report, the effects of air exposure on transition metal dichalcogenides (TMD)

2D transition metal dichalcogenides

Nature Reviews Materials, 2017
Graphene is very popular because of its many fascinating properties, but its lack of an electronic bandgap has stimulated the search for 2D materials with semiconducting character. Transition metal dichalcogenides (TMDCs), which are semiconductors of the type MX2, where M is a transition metal atom (such as Mo or W) and X is a chalcogen atom (such as S,

Intercalation of Metal into Transition Metal Dichalcogenides in Molten Salts

Small, 2023
AbstractVan der Waals (vdW)‐layered materials have drawn tremendous interests due to their unique properties. Atom intercalation in the vdW gap of layered materials can tune their electronic structure and generate unexpected properties. Here a chemical‐scissor‐mediated method that enables metal intercalation into transition metal dichalcogenides (TMDCs)

Transition Metal Dichalcogenides and Their Intercalates

International Reviews in Physical Chemistry, 1983
Abstract The transition metal dichalcogenides form a group of layered, highly anisotropic compounds which exhibit interesting and unusual physical properties. Compounds formed from the Group Iv, Group V and Group VI transition metals and from sulphur or selenium have been the subject of a great deal of interest in the past few years because of the ...

Synthesis of Transition Metal Dichalcogenides

2017
Novel properties and new phenomena that arise from two-dimensional (2D) materials have stimulated huge research interest recently. Among the 2D material family, semiconducting transition metal dichalcogenides (TMDCs) with an intrinsic band gap are complementary to the gapless graphene [1, 2]. Hence, both single-layer and multi-layer TMDCs are promising
