The inherent limitations of graphene in the context of electronic applications due to the absence of a band-gap can be overcome by combining it with materials that are intrinsically semiconducting (like the family of transition metal dichalcogenides) or insulating (like hexagonal boron nitride). Combinations of such materials in layered heterost...

In this talk, we present some new physical phenomena found in recent theoretical studies of atomically thin two-dimensional (2D) materials. Because of reduced dimensionality, interaction and symmetry effects as well as environmental screening effects dominate many properties of these systems, leading to manifestation of concepts and phenomena th...

Some of the most dramatic engineering feats accomplished with layered materials are enabled by properties that emerge only at the single or few-layer limit and are not found in bulk forms. I will discuss our efforts to elucidate useful emergent properties of monolayer and few-layer materials, including our predictions and several recent experime...

Surface-plasmon polaritons (SPPs) are evanescent electromagnetic waves of relatively short wavelength that may be excited on conducting, 2D materials. These waves are macroscopic manifestations of the coupling between the incident radiation and the electron plasma. In this talk, I will discuss recent analytical progress in understanding the effe...
