Abstract
Monolayer films of transition metal dichalcogenides can have very different electronic and structural properties compared to their bulk counterparts. Here, the authors stabilize different structural phases of VSe${}_{2}$ monolayer and bilayer films and study the effects on the electronic properties, charge density wave state, and magnetic properties, using a combination of techniques including scanning tunneling microscopy and first-principles calculations. They find that a new distorted 1$T$ phase can be stabilized in the films that is not found in the bulk compound.
