The shape of energy dispersions near the band-edges plays a decisive role in the transport
properties, especially the carrier mobility, of semiconductors. In this work, we design and …

We introduce trilayer and multilayer moiré heterostructures that cannot be viewed from the
“moiré-of-moiré” perspective of helically twisted trilayer graphene. These “intrinsically …

Emerging twistronics based on van der Waals (vdWs) materials has attracted great interest
in condensed matter physics. Recently, more neoteric three-dimensional (3D) architectures …

We theoretically study the electronic structure of interface states in twisted stacks of three-
dimensional topological insulators. When the center of the surface Dirac cone is located at a …

Motivated by recent experiments demonstrating the creation of atomically sharp interfaces
between hexagonal sapphire and cubic SrTiO 3 with finite twist, we here develop and study …

We study the energies and optical spectra of excitons in twisted bilayers of anisotropic van
der Waals semiconductors exhibiting moiré patterns, taking phosphorene as a case study …

Here we propose BC 3, a graphene derivative that has been synthesized, as a platform to
realize exotic quantum phases by introducing a moiré pattern with mismatched stacking. In …

Atomically thin group IV monochalcogenides or phosphorene analogues are a promising
family of materials. Theoretical calculations predict that monolayers (MLs) should be …
