The density of states of graphene underneath a metal electrode and its correlation with the contact resistivity
Ryota Ifuku, Kosuke Nagashio, Tomonori Nishimura +1
The density of states (DOS) of graphene underneath a metal is estimated through a quantum capacitance measurement of the metal/graphene/SiO2/n+-Si contact structure fabricated by a…
Carrier density modulation in graphene underneath Ni electrode
T. Moriyama, K. Nagashio, T. Nishimura +1
We investigate the transport properties of graphene underneath metal to reveal whether the carrier density in graphene underneath source/drain electrodes in graphene field-effect t…
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…
