An on-demand coherent single-electron source.
We report on the electron analog of the single-photon gun. On-demand single-electron injection in a quantum conductor was obtained using a quantum dot connected to the conductor via a tunnel barrier. Electron emission was triggered by the application of a potential step that compensated for the dot-charging energy. Depending on the barrier transparency, the quantum emission time ranged from 0.1...
متن کاملCoherent 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, particle-hole excitations can be suppressed for certain driving prot...
متن کاملSingle Crystal Diamond Needle as Point Electron Source
Diamond has been considered to be one of the most attractive materials for cold-cathode applications during past two decades. However, its real application is hampered by the necessity to provide appropriate amount and transport of electrons to emitter surface which is usually achieved by using nanometer size or highly defective crystallites having much lower physical characteristics than the i...

15 صفحه اولUltracold Electron Source for Ultrafast Electron Diffraction
Single-shot ultrafast electron diffraction (UED) was introduced as a viable way to measure ultrafast processes, such as structural transitions in materials. For UED, the dynamics in a sample are induced by a femtosecond laser pulse and ultrashort electron bunches are used to probe the ultrafast processes in the sample. The ultracold charged particle cloud (UCPC) source researched in this work i...
