Figure 2From: Temperature dependence of the electrical transport properties in few-layer graphene interconnectsTemperature-dependent current–voltage characteristics of (a) tri- and (b) four-layer graphene interconnects. Insets show the details of the low electric field measurements. For tri- and four-layer graphene, resistors show sublinear characteristics at low field (<0.01 V/μm) and superlinear I-V curve for the high field due to the heat effect.Back to article page
