| Research Abstract |
We have studied quantum well structures such as metal multi-layers and wire-like metal structures, by which the Kondo effect can be modulated and controlled. For metal multi-layers, we have found that the energy levels of quantum well states change systematically as a function of the width of the quantum well, and that the Kondo temperature and Fano's asymmetric parameter changes in accordance with it. We have also studied in detailed striped noble-metal film as a candidate for a wire-like metal structure. They were fabricated using a one-dimensional silicon surface reconstruction as a template. It was revealed that, due to the stacking fault arrays present in the striped film, the electrons in surface states are strongly confined and forms one-dimensional electronic states.
