▲ [14a-B414-4] Improving of Plasmon Controllability in Graphene by Electric or Magnetic Fields
キーワード：graphene, plasmon, spatial control
Tunability of graphene plasmons by external electric and magnetic fields will enable us to develop programmable plasmonic circuits and metamaterials. Beyond frequency tuning of a graphene plasmon cavity, which has been demonstrated in a variety of structures, we demonstrate active spatial control of graphene plasmons by tailoring carrier density profile [1]. We also show almost dissipationless plasmon transport in one-dimensional edge channels formed under a magnetic field [2].
