Despite their partial ionic nature, many-layered diatomic crystals avoid internal electric
polarization by forming a centrosymmetric lattice at their optimal van der Waals stacking …

Potential applications in photonics and optoelectronics are based on our understanding of
the light–matter interaction on an atomic monolayer scale. Atomically thin 2D transition metal …

Fabricating van der Waals bilayer heterostructures (BL-HS) by stacking the same or different
two-dimensional layers, offers a unique physical system with rich electronic and optical …

Recently, the twist angle between adjacent sheets of stacked van der Waals materials
emerged as a new knob to engineer correlated states of matter in two-dimensional …

Experimental advances in the fabrication and characterization of few-layer materials stacked
at a relative twist of small angle have recently shown the emergence of flat energy bands. As …

Having a direct optical band gap, monolayers of transition metal dichalcogenide (TMD)
nanosheets have attracted great attention due to their exceptional optical properties and …

Stacking two layers of two-dimensional materials slightly twisted relative to each other
causes significant alternations of the physical properties of the resulting bilayer. For …

We study the influence of strong spin-orbit interaction on the formation of flat bands in
relaxed twisted bilayer W Se 2. Flat bands, well separated in energy, emerge at the band …

We study the electronic structure and correlated phases of twisted bilayers of platinum
diselenide using large-scale ab initio simulations combined with the functional …

Abstract van der Waals materials are emerging due to their unique properties such as
atomic thickness, diverse quasiparticle optical resonances, and no requirement for lattice …
