Abstract

Heterostructures of atomically thin van der Waals bonded monolayers have opened a unique platform to engineer Coulomb correlations, shaping excitonic(1-3), Mott insulating(4) or superconducting phases(5,6). In transition metal dichalcogenide heterostructures(7), electrons and holes residing in different monolayers can bind into spatially indirect excitons(1,3,8-11) with a strong potential for ...
