Layer by layer assembly of two-dimensional materials enables the tailored fabrication of atomically thin electronic devices. By using different material combinations, these van der Waals heterostructures can possess novel properties not found in the constituent materials. For example, combining graphene with semiconductor materials in heterostructure photodetectors, allows the detection of light signals down to powers in the femtowatt range. Currently, the operational speed of these detectors is limited by the presence of long-lived charge traps to a few tens of Hz. In this work, we fabricate and fully characterize atomically thin graphene-WS 2 heterostructure photodetectors, encapsulated in an ionic polymer. we demonstrate an internal gain exceeding 10 6 electrons per photon due to the high mobility graphene channel and the strong light-matter interaction of WS 2 . However, unique to our devices is the …
