Waals MoS2/WSe2 heterojunctions. We observe room-temperature negative differential
resistance (NDR) in a heterojunction diode comprised of few-layer WSe2 stacked on
multilayer MoS2. The presence of NDR is attributed to the lateral band-to-band tunneling at
the edge of the MoS2/WSe2 heterojunction. The backward tunneling diode shows an
average conductance slope of 75 mV/dec with a high curvature coefficient of 62 V–1 …
This paper studies band-to-band tunneling in the transverse and lateral directions of van der
Waals MoS₂/WSe₂ heterojunctions. We observe room-temperature negative differential
