Memory Steps in Graphene
Figure (a) SEM image of a representative four-terminal graphene device. Figure (b) Memory steps at T=533 K (T=260 oC) observed in several different graphene transistors. Note that the step occurs near Vg ? 0 V despite the fact that graphene transistors had different shapes, charge neutrality points and electrical conductivities.
