Photodoping
WebJul 15, 1993 · The photodoping process in Ag/As30S70 layers excited by pulsed light has been studied. The photodoping begins within 0.1 μs after the pulse excitation, and the response amplitude and relaxation time exhibit similar characteristics to those of the transient photoconduction in amorphous As30S70 and AgAsS2. These observations … WebMay 23, 2024 · We present a device scheme to explore mesoscopic transport through molybdenum disulfide (MoS 2) constrictions using photodoping.The devices are based on van-der-Waals heterostructures where few-layer MoS 2 flakes are partially encapsulated by hexagonal boron nitride (hBN) and covered by a few-layer graphene flake to fabricate …
