Study of Structural and Electronic Properties of Intercalated Transition Metal Dichalcogenides Compound MTiS2 (M = Cr, Mn, Fe) by Density Functional Theory

open access: yesEast European Journal of Physics, 2021
In the present work, we have studied intercalated Transition Metal Dichalcogenides (TMDC) MTiS2 compounds (M = Cr, Mn, Fe) by Density Functional Theory (DFT) with Generalized Gradient Approximation (GGA).

Excitonic instability in transition metal dichalcogenides

open access: yesJournal of Physics: Condensed Matter, 2022
Abstract When transition-metal dichalcogenide monolayers lack inversion symmetry, their low-energy single particle spectrum near some high-symmetry points can, in some cases, be described by tilted massive Dirac Hamiltonians. The so-called Janus materials fall into that category.

Γ valley transition metal dichalcogenide moiré bands [PDF]

open access: yesProceedings of the National Academy of Sciences, 2021
Significance At small twist angles, moiré patterns form in transition metal dichalcogenide bilayers. Using sophisticated ab initio calculations, we develop a model able to describe the band structure of these systems. We found that the moiré pattern acts as a long-wavelength modulating potential, with a sixfold rotational symmetry not present

Longitudinal unzipping of 2D transition metal dichalcogenides

open access: yesNature Communications, 2020
Reliable unzipping of the basal plane of mono-elemental graphene and phosphorene has only been reported thus far. Here, the authors demonstrate the unzipping of bi-elemental 2D MX2 transition metal chalcogenides as a general route to synthesize 1D ...

Entropy per particle spikes in the transition metal dichalcogenides [PDF]

open access: yes, 2018
We derive a general expression for the entropy per particle as a function of chemical potential, temperature and gap magnitude for the single layer transition metal dichalcogenides.

Intrinsic Exciton Linewidth in Monolayer Transition Metal Dichalcogenides [PDF]

open access: yes, 2014
Monolayer transition metal dichalcogenides feature Coulomb-bound electron-hole pairs (excitons) with exceptionally large binding energy and coupled spin and valley degrees of freedom. These unique attributes have been leveraged for electrical and optical

Intervalley Scattering and Localization Behaviors of Spin-Valley Coupled Dirac Fermions [PDF]

open access: yes, 2013
We study the quantum diffusive transport of multivalley massive Dirac cones, where time-reversal symmetry requires opposite spin orientations in inequivalent valleys. We show that the intervalley scattering and intravalley scattering can be distinguished
