NOISE RECTIFIER BASED ON THE TWO-DIMENSIONAL ELECTRON GAS
Cheremisin M.V.
Поступила в редакцию: 2 Февраля 2012
The dc voltage observed at low temperatures in a 2D electron sample in the absence of noticeable external excitations [1] is accounted by the Schottky contact rectification of the noise generated in the measuring circuit. The rectified voltage is shown to depend on the asymmetry of the contact pair. The dependence of the rectified voltage on the noise amplitude first follows the trivial quadratic law, then exhibits a nearly linear behavior, and finally, levels off.
