Gate tunable graphene-silicon Ohmic/Schottky contacts

(author unknown)



Chun-Chung Chen, Chia-Chi Chang, and Zhen Li et al.

We show that the I-V characteristics of graphene-silicon junctions can be actively tuned from rectifying to Ohmic behavior by electrostatically doping the graphene with a polymer electrolyte gate. Under zero applied gate voltage, we observe rectifying I-V characteristics, demonstrating the formati ... [Appl. Phys. Lett. 101, 223113 (2012)] published Thu Nov 29, 2012.
