Coherent Particle Transfer in an On-Demand Single-Electron Source
Coherent Particle Transfer in an On-Demand Single-Electron Source
Electron transfer from a localized state in a quantum dot into a ballistic conductor generally results in particle-hole excitations. We study this effect, considering a resonance level with time-dependent energy coupled to particle states in the Fermi sea. We find that, as the resonance level is driven through the Fermi-level, …
