Interlayer excitons diffusion and transport in van der Waals heterostructures

Materials Futures
The assembly of monolayer transition metal dichalcogenides (TMDs) in van der Waals heterostructures yields the formation of spatially separated interlayer excitons (IXs) with large binding energies, long lifetimes, permanent dipole moments and valley ...

Twistronics and moiré excitonic physics in van der Waals heterostructures

Frontiers of Physics
AbstractHeterostructures composed of two-dimensional van der Waals (vdW) materials allow highly controllable stacking, where interlayer twist angles introduce a continuous degree of freedom to alter the electronic band structures and excitonic physics.

Opto-twistronic Hall effect in a three-dimensional spiral lattice

Nature
Studies of moire systems have elucidated the exquisite effect of quantum geometry on the electronic bands and their properties, leading to the discovery of new correlated phases. However, most experimental studies have been confined to a few layers in the 2D limit. The extension of twistronics to its 3D limit, where the twist is extended into the third
