Experimental test of the correction terms for Coulomb blockade thermometry
Journal article, 2004
The higher-order correction terms for Coulomb blockade thermometry were investigated using two-dimensional (2D) arrays of small tunnel junction. The measurements of the I-V characteristics of three 2D arrays of tunnel junctions at different temperatures were reported. The results from the investigated were compared with theory of one-dimensional (1d) arrays. It was observed that correction term was independent of temperature. The correction term for the conductance tip was found to be two times smaller than the value predicted by 1D theory.
