Electrical transport properties of graphene on SiO2 with specific surface structures
K. Nagashio, T. Yamashita, T. Nishimura +2
The mobility of graphene transferred on a SiO2/Si substrate is limited to ~10,000 cm2/Vs. Without understanding the graphene/SiO2 interaction, it is difficult to improve the electr…
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…
Systematic Investigation of the Intrinsic Channel Properties and Contact Resistance of Monolayer and Multilayer Graphene FET
Kosuke Nagashio, Tomonori Nishimura, Koji Kita +1
The intrinsic channel properties of monolayer and multilayer graphene were systematically investigated as a function of layer number by the exclusion of contact resistance using fo…
Mobility variations in mono- and multi-layer graphene films
Kosuke Nagashio, Tomonori Nishimura, Koji Kita +1
The electric properties of mono- and multi-layer graphene films were systematically studied with the layer number determined by their optical contrast. The current modulation incre…
