Radius-voltage relation of graphene bubbles controlled by gate voltage

Weihua Mu, Gang Zhang, and Zhong-can Ou-Yang

Graphene on the substrate can form bubbles rising above the sheet. In some cases, the bubbles is a perfect spherical surface crown, and its radius can be adjusted by external electric field. In this manuscript, we theoretically investigate the voltage dependence of the spherical bubble's radius. T ... [Appl. Phys. Lett. 103, 053112 (2013)] published Wed Jul 31, 2013.
