Defect-induced states, defect-induced phase transition and excitonic states in bent transition metal dichalcogenide (TMD) nanoribbons: density functional vs. many body theory
Santosh Neupane, Hong Tang, Adrienn Ruzsinszky
Two-dimensional (2D) transition metal dichalcogenide (TMD) materials have versatile electronic and optical properties. TMD nanoribbons show interesting properties due to reduced di…
Spin-polarization anisotropy included by mechanical bending in tungsten diselenide nanoribbons and tunable excitonic states
Hong Tang, Santosh Neupane, Li Yin +2
A WSe monolayer shows many interesting properties due to its spin-orbit coupling induced spin splitting in bands around the Fermi level and the spin-valley configuration. The o…
Controllable optical and magneto-optical properties of magnetic CrI3 nanoribbons
Hong Tang, Santosh Neupane, Qimin Yan +1
A monolayer of CrI3 has an amazing ferromagnetic ground-state. In this work, we calculate band structures and magnetic moments of tensile-strained and bent zigzag CrI3 nanoribbons…
Tunable band gaps and optical absorption properties of bent MoS nanoribbons
Hong Tang, Bimal Neupane, Santosh Neupane +3
The large tunability of band gaps and optical absorptions of armchair MoS nanoribbons of different widths under bending is studied using density functional theory and many-body…
Understanding plasmon dispersion in nearly-free-electron metals: the relevance of exact constraints for novel exchange-correlation kernels within time-dependent density functional theory
Niraj K. Nepal, Santosh Adhikari, Bimal Neupane +3
Small-wavevector excitations in Coulomb-interacting systems can be decomposed into the high-energy collective longitudinal plasmon and the low-energy single-electron excitations. A…
