Interlayer excitons in transition metal
dichalcogenides (TMDs) van der Waals (vdW) heterostructures exhibit
fascinating physics and hold great promise for developing excitonic
devices. Scientists in China present a systematical and
comprehensive overview of the interlayer exciton formation,
relaxation, transport, and potential applications of TMDs vdW
heterostructures, in order to provide valuable guidance for new
researchers in this field as well as to present the most important
issues present in the field for future deep studies.
