Emerging Two Dimensional Van Der Waals Materials for Optical Information Transfer and Processing
Abstract
The research will addressed the following topics: Light-matter interactions and collective quantum dynamics by considering the quantum kinetics of coupled charges and photons and the interaction with phonons, to understand the charge and photon transport in transition-metal dichalcogenides (TMDC) based structures; Collective quantum phenomena in two-dimensional van der Waals materials such as TMDC, Xenes (silicene, germanene, and stanene), phosphorene, transition-metal trichalcogenides, including Bose-Einstein condensation and superfluidity of excitons and cavity polaritons in these materials; Influence of the reduction of dimensionality on the binding energy of excitons, trions and biexcitons in bulk and low dimensional semiconductors; Optical properties of excitons in buckled two-dimensional materials in an external electric field; Low-energy consumption room-temperature optoelectronic devices by considering the coupled charge and photon dynamics in multilayered structures. We will obtain and analyze the polariton flow induced by the spin flow due to spin Hall effect for excitons in TMDC. We propose to study the effects of a periodic potential on a superfluid of excitons and polaritons, formed by excitons, in a TMDC monolayer. Optimizing room-temperature polaritonic circuit performance. The obtained knowledge of van der Waals materials mono- and double-layer systems, and their interactions with light will be harnessed to find the conditions and geometries for optimal performance of active optoelectronic and spintronic systems.
