Defect-assisted high photoconductive UV-VIS gain in perovskite-decorated graphene transistors (2019)
Journal Article

Recent progress in the synthesis of high stability inorganic perovskite nanocrystals (NCs) has led to their increasing use in broadband photodetectors. These NCs are of particular interest for the UV range as they have the potential to extend the wav...

Magnetophonon spectroscopy of Dirac fermion scattering by transverse and longitudinal acoustic phonons in graphene (2019)
Journal Article

Recently observed magnetophonon resonances in the magnetoresistance of graphene are investigated using the Kubo formalism. This analysis provides a quantitative fit to the magnetophonon resonances over a wide range of carrier densities. It demonstrat...

Two-Dimensional Covalent Crystals by Chemical Conversion of Thin van der Waals Materials (2019)
Journal Article

Most of the studied two-dimensional (2D) materials have been obtained by exfoliation of van der Waals crystals. Recently, there has been growing interest in fabricating synthetic 2D crystals which have no layered bulk analogues. These efforts have be...

Strong magnetophonon oscillations in extra-large graphene (2019)
Journal Article

Van der Waals materials and their heterostructures offer a versatile platform for studying a variety of quantum transport phenomena due to their unique crystalline properties and the exceptional ability in tuning their electronic spectrum. However, m... Read More about Strong magnetophonon oscillations in extra-large graphene.

Direct band-gap crossover in epitaxial monolayer boron nitride (2019)
Journal Article

Hexagonal boron nitride is a large band-gap insulating material which complements the electronic and optical properties of graphene and the transition metal dichalcogenides. However, the intrinsic optical properties of monolayer boron nitride remain... Read More about Direct band-gap crossover in epitaxial monolayer boron nitride.
