What is the Fastest Speed at which a Single Electron Can Be Detected?
Deepak S. Rao, Thomas Szkopek, HongWen Jiang +1
Electrometers measure electric charge, but there must be a fundamental speed limit to measuring one electric charge. Since there are no dimensional inputs to this question, the ans…
Single photo-electron trapping, storage, and detection in a one-electron quantum dot
Deepak Sethu Rao, Thomas Szkopek, Hans Daniel Robinson +2
There has been considerable progress in electro-statically emptying, and re-filling, quantum dots with individual electrons. Typically the quantum dot is defined by electrostatic g…
A single photoelectron transistor for quantum optical communications
Hideo Kosaka, Deepak S. Rao, Hans D. Robinson +3
A single photoelectron can be trapped and its photoelectric charge detected by a source/drain channel in a transistor. Such a transistor photodetector can be useful for flagging th…
Photoconductance Quantization in a Single-Photon Detector
Hideo Kosaka, Deepak S. Rao, Hans D. Robinson +3
We have made a single-photon detector that relies on photoconductive gain in a narrow electron channel in an AlGaAs/GaAs 2-dimensional electron gas. Given that the electron channel…
