Coulomb blockade thermometry using a two-dimensional array of tunnel junctions
arXiv:cond-mat/0012244 · doi:10.1063/1.371296
Abstract
We have measured current-voltage characteristics of two-dimensional arrays of small tunnel junctions at temperatures from 1.5 K to 4.2 K. This corresponds to thermal energies larger than the charging energy. We show that 2D-arrays can be used as primary thermometers in the same way as 1D-arrays, and even have some advantages over 1D-arrays. We have carried out Monte Carlo simulations, which agree with our experimental results.
