We present a low-cost ultra-low-noise cryogenic amplifier, which has been developed for the investigation of shot noise suppression and enhancement in double-barrier resonant-tunneling devices. Results of the noise measurements performed on the amplifier operating at liquid nitrogen temperature are discussed and compared to those obtained at room temperature.

Abstract
We present a low-cost ultra-low-noise cryogenic amplifier, which has been developed for the investigation of shot noise suppression and enhancement in double-barrier resonant-tunneling devices. Results of the noise measurements performed on the amplifier operating at liquid nitrogen temperature are discussed and compared to those obtained at room temperature.File in questo prodotto:
