Twist-tailoring Coulomb correlations in van der Waals homobilayers

Twist-tailoring Coulomb correlations in van der Waals homobilayers

The crystallographic orientation of monolayers in van der Waals multi-layers controls their electronic and optical properties. Here the authors show how the twist angle affects Coulomb correlations governing the internal structure and the mutual interaction of excitons in homobilayers of WSe2.
