Quantitative Raman Spectrum and Reliable Thickness Identification for Atomic Layers on Insulating Substrates
Song-Lin Li, Hisao Miyazaki, Haisheng Song +3
We demonstrate the possibility in quantifying the Raman intensities for both specimen and substrate layers in a common stacked experimental configuration and, consequently, propose…
Unipolar transport in bilayer graphene controlled by multiple p-n interfaces
Hisao Miyazaki, Song-Lin Li, Shu Nakaharai +1
Unipolar transport is demonstrated in a bilayer graphene with a series of p-n junctions and is controlled by electrostatic biasing by a comb-shaped top gate. The OFF state is induc…
Gate-Controlled P-I-N Junction Switching Device with Graphene Nanoribbon
Shu Nakaharai, Tomohiko Iijima, Shinichi Ogawa +5
The concept of a novel graphene P-I-N junction switching device with a nanoribbon is proposed, and its basic operation is demonstrated in an experiment. The concept aims to optimiz…
Observation of Tunneling Current in Semiconducting Graphene p-n Junctions
Hisao Miyazaki, Michael Lee, Song-Lin Li +3
We demonstrate a tunneling and rectification behavior in bilayer graphene. A stepped dielectric top gate creates a spatially modulated electric field, which opens the band gap in t…
Complementary-like Graphene Logic Gates Controlled by Electrostatic Doping
Song-Lin Li, Hisao Miyazaki, Michael V. Lee +3
Realization of logic circuits from graphene is very attractive for high-speed nanoelectronics. However, the intrinsic ambipolar nature hinders the formation of graphene logic devic…
Enhanced Logic Performance with Semiconducting Bilayer Graphene Channels
Song-Lin Li, Hisao Miyazaki, Hidefumi Hiura +2
Realization of logic circuits in graphene with an energy gap (EG) remains one of the main challenges for graphene electronics. We found that large transport EGs (>100 meV) can be f…
