Abstract
A negative differential resistance (NDR) device, and methods of making and using the NDR device. The NDR device includes a substrate comprising a conductor material or a semi-conductor material and a self-assembled monolayer (SAM) that includes a first electroactive moiety and a spacer moiety disposed on the substrate that defines a barrier between the electroactive moiety and the substrate, wherein the NDR device exhibits negative differential resistance in the presence of a varying applied voltage. Also provided are NDR in multilayers in which the peak to valley ratio of the NDR response can be controlled by the number of layers; modulation of NDR using binding groups to one of the electrical contacts or to the electroactive moiety itself; and NDR devices that display multiple peaks in the current-voltage curve that contain electroactive moieties that have multiple low potential electrochemical oxidations and/or reductions.
