Abstract

We realized high quality tunnel junctions using bcc-bcc Mo-Ta superlattices in the modulation wavelength range 16–450 Å as the first electrode. The dV/dI vs. V characteristics showed a double peak structure in the wavelength range 50–250 Å. We fitted the temperature behavior of these structures using both a two band model and the proximity effect theory. Preliminary calculations of a possible microscopic explanation of this data are presented.
