24 Jul 2003 | Subject: | Superconductivity | cond-mat.supr-con | Abstract: | We examine a building block for logic devices in which the positions of superconducting vortices in coupled elongated antidots provide the elementary logic states of 0 and 1. We show analytically and through simulation the maximum operating frequency of a pair of antidots as a function of antidot spacing and elongation. At finite temperatures, a signal can propagate through a series of identically shaped antidots with correctly chosen spacing, with an exponential distribution of switching times for the signal to move over by one antidot. | Source: | arXiv, cond-mat/0307596 | Services: | Forum | Review | PDF | Favorites |
