Probing Dirac Electron Physics in Graphitic Materials
- 00:49:06
Description |
|---|
|
Electrons in monolayer graphene are described by massless Dirac electrons, which exhibit unique quantum phenomena due to the pseudospin and Berry phase of the massless electrons. In this talk, I will discuss our effort in probing massive Dirac electrons in gapped bilayer graphene, where a finite mass can be continuously engineered and a mass domain wall with topologically protected transport can be realized. I will also discuss one-dimensional plasmon arising from Luttinger liquid of Dirac electrons in metallic carbon nanotubes, which exhibit semi-quantized propagation speed and remarkable sub-wavelength plasmon confinement. |
