Abstract
We suggest and demonstrate in experiment that two normal metal/insulat or/superconductor (NIS) tunnel junctions combined in series to form a symmetric SINIS structure can operate as an efficient Peltier refriger ator. Specifically, it is shown that the SINIS structure with normal-s tate junction resistances 1.0 and 1.1 k Omega is capable of reaching a temperature of about 100 mK starting from 300 mK. We estimate the cor responding cooling power to be 1.5 pW per total junction area of 0.8 m u m(2) at T = 300 mK. (C) 1996 American Institute of Physics.
