摘      要：We have measured current-voltage characteristics of a two-dimensional array of small tunnel junctions at temperatures from 1.4 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 have several advantages over 1D-arrays. (C) 2000 Elsevier Science B.V. All rights reserved.
