The stability of a graphene field effect transistor(GFET) is important to its performance optimization, and study of hysteresis behavior can propose useful suggestions for GFET fabrication and optimization.In this w...
We show the fabrication of flexible graphene devices with an embedded backgate. The resistance of these devices can be tuned by changing the strain through the bending of the substrate. These devices can be useful for...
