Graphene negative differential resistance (GNDR) circuit with enhanced performance at room temperature

Mihai Adrian Ionescu, Arnaud Magrez, Laurent Syavoch Bernard, Antonios Bazigos, Pankaj Sharma

We propose and experimentally demonstrate a novel circuit based on graphene FETs (GFETs) showing excellent negative differential resistance (NDR) characteristics at room temperature. The proposed GNDR circuit exploits a closed loop connection of 1-GFET wit ...
