Figure 2. Electrical characterization of CVD h-BN tunnel barrier.

Figure 2

(a) Three-terminal I-V characteristics of high resistance (HR) and low resistance (LR) h-BN (Co|h-BN|Graphene) contacts at room temperature. The current for the HR contact is scaled by a factor of 10 to highlight the non-linearity with bias. Inset: As measured I-V curve of the HR contact in a higher current-voltage range. (b) Temperature dependent I-V characteristics for the LR h-BN contact at 1.5 and 300 K. Inset: Temperature dependence of the HR h-BN contact resistance at zero bias (ZBR) and 300 mV.
