Influence of electron-hole drag on conductivity of neutral and gated graphene
Influence of electron-hole drag gated graphene
2010/11/18
Conductivity of monolayer and two-layer graphene is considered with due regard for mutual drag of band elec-trons and holes. Search of contribution of the drag in conductivity shows that this effect c...
Dephasing of Entangled Electron-Hole Pairs in a Degenerate Electron Gas
Entanglement Bell inequality Nonlocality Decoherence
2010/4/12
A tunnel barrier in a degenerate electron gas was recently discovered as a source of entangled electron-hole pairs. Here, we investigate the loss of entanglement by dephasing. We calculate both the ma...
