Acoustic phonon recycling for photocarrier generation in graphene-WS2 heterostructures

Acoustic phonon recycling for photocarrier generation in graphene-WS2 heterostructures

Here, the authors perform transient absorption microscopy on graphene-WS2 heterostructures, and identify a phonon recycling process that couples the heat generated in graphene back into the carrier distribution in WS2 with a picosecond characteristic time.
