Vt. Petrashov et al., THERMAL EFFECT IN PHASE-PERIODIC ELECTRON-TRANSPORT IN DISORDERED MESOSCOPIC NORMAL-METAL SUPERCONDUCTOR STRUCTURES, Czechoslovak journal of Physics, 46, 1996, pp. 2327-2328
We report measurements of the temperature dependence of the amplitude
of phase-periodic conductance oscillations in disordered normal metal
(Ag) structures, attached to a superconducting (Al) wire at two points
. The amplitude of oscillations reaches its maximum at temperatures, T
, when the Thouless energy is of the order of k(B)T. The results are
in agreement with recent calculations by Nazarov and Stoof [Phys. Rev.
Lett. 76 (1996) 823].
