Abstract: Transition metal dichalcogenides (TMDs) have received significant attention owing to their thickness-dependent folded current–voltage (Ids–Vds) characteristics, which offer various threshold voltage values. Owing to these astonishing characteristics, TMDs based negative differential resistance (NDR) devices are… read more here.

Abstract: We demonstrate low energy, forming and compliance-free operation of a resistive memory obtained by the partial oxidation of a two-dimensional layered van-der-Waals semiconductor: hafnium disulfide (HfS2). Semiconductor-oxide heterostructures are achieved by low temperature ( read more here.
