Abstract: Charge-transfer transitions enhance carrier generation at the interfaces of two-dimensional heterostructures. Efficient interfacial carrier generation in van der Waals heterostructures is critical for their electronic and optoelectronic applications. We demonstrate broadband photocarrier generation in WS2-graphene… read more here.
