Physical and Technology for the Investigation of Properties of Ultra Small Systems
Abstract
In superconducting thin films, the long range proximity effect and the observation of a novel resistance anomaly are new physical phenomena exposed through the development of a technique to precisely modify the transition temperature in a well defined region. Free standing metallic structures were fabricated to understand thermal transport in thin films. In this latter work, the electron-phonon interaction should be modified due to the thermal cut-off of excitations. Using two different techniques, we have determined that the electron-phonon interaction does not display the expected thermal cut-off, a fact which may be of significance in thermalizing electronic components. We have also observed a reduction of the electron-impurity-spin interaction due to size effects, which should have interesting consequences for the magnetism of ultrasmall structures.
