Abstract :
The quantum resistance and capacitance of a mesoscopic RC circuit made of a small dot connected to a lead by a QPC realized in a 2DEG are measured for the first time. Contrary to what can be naively expected, in the coherent regime the resistance is not given by the Landauer formula but is nearly constant and is found to be close to half the resistance according to Buttikerʹs AC quantum scattering theory.
