In this paper we briefly discuss the current provisional temperature scale of 2000 (PLTS-2000) for low temperatures. Electronic
thermometry is presented and discussed, focusing on its potential in verifying and realizing a future temperature scale. The
discussion covers secondary thermometers such as NIS and SIS thermometers and noise, shot noise and Coulomb blockade primary
thermometers. The last one is discussed in more detail. 相似文献

We present a quantum calculation based on scattering theory of the frequency-dependent noise of current in an interacting chaotic cavity. We include interactions of the electron system via long range Coulomb forces between the conductor and a gate with capacitance C. We obtain explicit results exhibiting the two time scales of the problem, the cavity's dwell time tau(D) and the RC time tau(C) of the cavity in relation to the gate. The noise shows peculiarities at frequencies of the order and exceeding the inverse charge relaxation time tau(-1) = tau(D)(-1) + tau(C)(-1). 相似文献
