      abstract     = {We present a device scheme to explore mesoscopic transport
                      through molybdenum disulfide (MoS2) constrictions using
                      photodoping. The devices are based on van-der-Waals
                      heterostructures where few-layer MoS2 flakes are partially
                      encapsulated by hexagonal boron nitride (hBN) and covered by
                      a few-layer graphene flake to fabricate electrical contacts.
                      Since the as-fabricated devices are insulating at low
                      temperatures, we use photo-induced remote doping in the hBN
                      substrate to create free charge carriers in the MoS2 layer.
                      On top of the device, we place additional metal structures,
                      which define the shape of the constriction and act as shadow
                      masks during photodoping of the underlying MoS2/hBN
                      heterostructure. Low temperature two- and four-terminal
                      transport measurements show evidence of quantum confinement
                      effects.},
