Trapping electrons in electrostatic traps over the surface of helium
We have observed trapping of electrons in an electrostatic trap formed over
the surface of liquid helium-4. These electrons are detected by a Single
Electron Transistor located at the centre of the trap. We can trap any desired
number of electrons between 1 and . By repeatedly (
times) putting a single electron into the trap and lowering the electrostatic
barrier of the trap, we can measure the effective temperature of the electron
and the time of its thermalisation after heating up by incoherent radiation.Comment: Presented at QFS06 - Kyoto, to be published in J. Low Temp. Phys., 6
