Abstract

IN this paper some observations are presented on an anomalous current in aluminum-carbon-aluminium (Al-C-Al) sandwiches, at room temperature, which in several respects behaves in the same way as the Josephson current might be expected to do. At first the switching effect was studied in Al-C-Al sandwiches discovered by Ovshinsky1 and Pearson2 in chalcogenide glasses and amorphous oxides. In carbon sandwiches subjected to proper electrical pulsing, changes in resistance of a factor of 1,000 were found, the changes being reversible and with a memory time of the order of a few days3.
