Determination of Carrier Type Doped from Metal Contacts to Graphene by Channel-Length-Dependent Shift of Charge Neutrality Points
Ryo Nouchi, Tatsuya Saito, Katsumi Tanigaki
A method for determining the type of charge carrier, electron or hole, which is transferred from metal contacts to graphene, is described. The Dirac point is found to shift toward…
Transfer Characteristics in Graphene Field-Effect Transistors with Co Contacts
Ryo Nouchi, Masashi Shiraishi, Yoshishige Suzuki
Graphene field-effect transistors with Co contacts as source and drain electrodes show anomalous distorted transfer characteristics. The anomaly appears only in short-channel devic…
Robustness of Spin Polarization in Graphene-based Spin Valves
Masashi Shiraishi, Megumi Ohishi, Ryo Nouchi +3
Decrease of spin polarization in spintronics devices under an application of bias voltage is one of currently important problems which should be solved. We reveal unprecedented rob…
A Nuclear Magnetic Resonance Study on Rubrene-cobalt Nano-composites
Masashi Shiraishi, Haruka Kusai, Ryo Nouchi +5
We implemented a nuclear magnetic resonance (NMR) study on rubrene(C42H28)-Co nano-composites that exhibit an enhanced magnetoresistance (MR) ratio of 80%. The 59Co NMR spin echo e…
Logic Ciucuits Using Solution-processed Single-walled Carbon Nanotue Transistors
Ryo Nouchi, Haruo Tomita, Akio Ogura +2
This letter reports on the realization of logic circuits employing solution-processed networks of single-walled carbon nanotubes. We constructed basic logic gates (inverter, NAND a…
Spin Injection into a Graphene Thin Film at Room Temperature
Megumi Ohishi, Masashi Shiraishi, Ryo Nouchi +3
We demonstrate spin injection into a graphene thin film with high reliability by using non-local magnetoresistance (MR) measurements, in which the electric current path is complete…
