HfN2 monolayer for Valleytronics

Coupled spin and valley polarization in monolayer HfN2 and valley-contrasting physics at the HfN2 − WSe2 interface

This work, performed by Mr. Manish Kumar Mohanta and Prof. Abir De Sarkar, introduces the HfN2 monolayer as an exceptionally promising valleytronic material having valley properties complementary to that of Group VI TMDC. This is a report on valley contrasting physics and valley spin splitting (VSS) at the conduction band (CB), which would strongly motivate experimentalists to synthesize and explore this predicted two-dimensional material.
