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…
