Can freestanding Xene monolayers behave as excitonic insulators?
Matthew N. Brunetti, Oleg L. Berman, Roman Ya. Kezerashvili
We predict a phase transition in freestanding monolayer Xenes from the semiconducting phase to the excitonic insulating (EI) phase can be induced by reducing an external electric f…

On the Optical Properties of Excitons in Buckled 2D Materials in an External Electric Field
Matthew N Brunetti, Oleg L. Berman, Roman Ya. Kezerashvili
We study the binding energies and optical properties of direct and indirect excitons in monolayers and double layer heterostructures of Xenes: silicene, germanene, and stanene. It…
