Bending effects and optical properties of WSe2 nanoribbons of topological phase
Hong Tang, Jason M. Breslin, Li Yin +1
A WSe2 monolayer of 1T' phase is a large band gap quantum spin Hall insulator, supporting dissipationless charge and spin transports through the topologically protected edge states…

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…

Bending as a control knob for the electronic and optical properties of phosphorene nanoribbons
Bimal Neupane, Hong Tang, Niraj K. Nepal +1
We have assessed mechanical bending as a powerful controlling tool for the electronic structure and optical properties of phosphorene nanoribbons. We use state-of-the-art density f…
