摘要
We have applied single-electron transistors (SETs) for the measurement of the energy gap of a quasiparticle as a function of magnetic field in mesoscopic superconductors. Through the measurements, it turned out that the randomness results in the pinning force of vortices, though the configuration of the order parameter is dominated by the edge nucleation of the superconductivity. The pinning of vortex in the Coulomb island enabled us to explore the energy spectra of metastable states with a fixed number of fluxoids. (C) 1998 Elsevier Science Ltd. All rights reserved.
