Abstract

We have solved time-dependent Ginzburg-Landau equation for the nano-scaled composite structures of a high-Tc d-wave superconductor and a conventional s-wave superconductor, which is called d-dot, by the finite elemental method. We show the numerical simulation of transfer of the information among several d-dots. And we examined the transition time between two d-dots as a function of the external current.
