Polarizability, plasmons, and screening in 1T${}^{\prime }$-MoS${}_2$ with tilted Dirac bands

Antonios Balassis, Godfrey Gumbs, Oleksiy Roslyak

In the presence of an external vertical electric field and strain, it is evident that 1T${}^{\prime }$-MoS${}_2$ exhibits tilted Dirac bands which are valley-spin-polarized. Additionall…
