A Mechanical–Electrical Model to Describe the Negative Differential Resistance in Membranotronic Devices

Membranotronics Membranotronic devices rely on the emergence of negative differential resistance (NDR). In article number 2300397, Daniil Karnaushenko and co‐workers provide a model for simulating the current–voltage characteristic of such devices that consist of a membrane featuring a hole through which ionic current flows. Due to electrostatic pressure, the membrane deforms and the hole closes leading to NDR as observed in experiment. The cover picture shows a sketch of the current–voltage characteristic as well as the membrane in different states of its deformation.
