Query: S-type Negative Differential Resistance in Semiconducting
  Transition-Metal Dichalcogenides   Current-controlled (also known as "S-type") negative differential resistance
(NDR) is of crucial importance to many emerging applications including
neuromorphic computing and high-density memristors integration. However, the
experimental realization of S-type NDR based on conventional mechanisms poses
demanding requirements on materials, which greatly limits their potential
applications. Here, we experimentally identify that semiconducting transition
metal dichalcogenides (TMDs) can host a bipolar S-type NDR devices. Theoretical
simulations indicate that the origin of the NDR in these devices arises from a
thermal feedback mechanism. Furthermore, we demonstrate the potential
applications of TMDs based S-type NDR device in signal processing and
neuromorphic electronics.
