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…
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…
