Estimation of residual carrier density near the Dirac point in graphene through quantum capacitance measurement
K. Nagashio, T. Nishimura, A. Toriumi
We discuss the residual carrier density (n*) near the Dirac point (DP) in graphene estimated by quantum capacitance (CQ) and conductivity measurements. The CQ at the DP has a finit…

Contact resistivity and current flow path at metal/graphene contact
K. Nagashio, T. Nishimura, K. Kita +1
The contact properties between metal and graphene were examined. The electrical measurement on a multiprobe device with different contact areas revealed that the current flow prefe…
