Twistronics in two-dimensional transition metal dichalcogenide (TMD)-based van der Waals interface.

ABSTRACT: Transition metal dichalcogenides (TMD) based heterostructures have gained significant attention lately because of their distinct physical properties and potential uses in electronics and optoelectronics. In the present work, the effects of twist on the structural, electronic, and optical properties (such as the static dielectric constant, refractive index, extinction coefficient, and absorption coefficient) of vertically stacked TMD heterostructures, namely MoSe₂/WSe₂, WS₂/WSe₂, MoSe₂/WS₂ and MoS₂/WSe₂, have been systematically studied and a thorough comparison is done among these heterostructures. In addition, the absence of negative frequency in the phonon dispersion curve and a low formation energy c
