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...

The effects of crossed electric and magnetic fields on the electronic and exciton properties in semiconductor heterostructures have been investigated within the effective-mass and parabolic band appro...
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...
