Reduced Variability in Threshold Switches Using Heterostructures of SiO and Vertically Aligned MoS

Jimin Lee, Rana Walied Ahmad, Sofía Cruces +7

Layered two-dimensional (2D) materials provide unique structural features, such as physical gaps between their layers that are only connected through van der Waals (vdW) forces. Th…

Threshold Switching in Vertically Aligned MoS/SiO Heterostructures based on Silver Ion Migration

Jimin Lee, Rana Walied Ahmad, Sofía Cruces +7

Threshold switching (TS) is a phenomenon where non-permanent changes in electrical resistance of a two-terminal device can be controlled by modulating the voltage bias. TS based on…
