Suppression of nucleation density in twisted graphene domains grown on graphene/SiC template by sequential thermal process
Yao Yao, Taiki Inoue, Makoto Takamura +2
We investigated the growth of twisted graphene on graphene/silicon carbide (SiC-G) templates by metal-free chemical vapor deposition (CVD) through a sequential thermal (ST) process…
Active spatial control of terahertz graphene plasmons by tailoring carrier density profile
Ngoc Han Tu, Katsumasa Yoshioka, Satoshi Sasaki +3
Graphene offers a possibility for actively controlling plasmon confinement and propagation by tailoring its spatial conductivity pattern. However, implementation of this concept ha…
Plasmon Confinement by Carrier Density Modulation in Graphene
Ngoc Han Tu, Makoto Takamura, Yui Ogawa +2
We investigate plasmon resonances in graphene with periodic carrier density modulation. The period is 8 um, and each period consists of 1.7- and 6.3-um-wide ribbons with different…
Revealing the nature of defects in quasi free standing mono-layer graphene on SiC(0001) by means of Density Functional Theory
Tommaso Cavallucci, Yuya Murata, Makoto Takamura +3
Quasi free standing monolayer graphene (QFMLG) grown on SiC by selective Si evaporation from the Si-rich SiC(0001) face and H intercalation displays irregularities in STM and AFM a…
Atomic and Electronic Structure of Si Dangling Bonds in Quasi-Free-Standing Monolayer Graphene
Yuya Murata, Tommaso Cavallucci, Valentina Tozzini +7
Si dangling bonds without H termination at the interface of quasi-free standing monolayer graphene (QFMLG) are known scattering centers that can severely affect carrier mobility. I…
Bilayer-induced asymmetric quantum Hall effect in epitaxial graphene
Andrea Iagallo, Shinichi Tanabe, Stefano Roddaro +8
The transport properties of epitaxial graphene on SiC(0001) at quantizing magnetic fields are investigated. Devices patterned perpendicularly to SiC terraces clearly exhibit bilaye…
Correlation between morphology and transport properties of quasi-free-standing monolayer graphene
Yuya Murata, Torge Mashoff, Makoto Takamura +4
We investigate the morphology of quasi-free-standing monolayer graphene (QFMLG) formed at several temperatures by hydrogen intercalation and discuss its relationship with transport…
Hydrogen storage with titanium-functionalized graphene
Torge Mashoff, Makoto Takamura, Shinichi Tanabe +3
We report on hydrogen adsorption and desorption on titanium-covered graphene in order to test theoretical proposals to use of graphene functionalized with metal atoms for hydrogen…
Tuning of quantum interference in top-gated graphene on SiC
Andrea Iagallo, Shinichi Tanabe, Stefano Roddaro +3
We report on quantum-interference measurements in top-gated Hall bars of monolayer graphene epitaxially grown on the Si face of SiC, in which the transition from negative to positi…
