Optical Properties of Anisotropic Excitons in Phosphorene
Matthew N. Brunetti, Oleg L. Berman, Roman Ya. Kezerashvili
We study the eigenenergies and optical properties of both direct excitons in a phosphorene monolayer in different dielectric environments, and indirect excitons in heterostructures…
High-temperature tunable superfluidity of polaritons in Xene monolayers in an optical microcavity
Matthew N. Brunetti, Oleg. L. Berman, Roman Ya. Kezerashvili
We study tunable polaritons in monolayers of silicene, germanene, and stanene (Xenes) via an external electric field in an open optical microcavity whose length can be adjusted. An…
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…
