Magnetoelectric flat band induced by a $\sqrt{3}\times \sqrt{3}$ charge density wave in monolayer CrSe${}_2$

Pablo Savino, M. del Carmen Fuente Santiago, Jan Phillips +4

We investigate the electronic and magnetic properties of the polar $\sqrt{3}\times \sqrt{3}$ charge-density-wave (CDW) phase of CrSe${}_2$ using ab initio calculations. The CDW introd…
