Outline of Final Research Achievements |
The s-electrons of alkali metals are assigned to the ideal free-electron system, but they display novel properties in the regular nanospaces of zeolite crystals. These s-electrons are quantized in the nanoclusters in zeolite cages, and have an electron correlation due to the mutual Coulomb repulsion and also the electron-phonon interaction due to the displacement of alkali cations. As the results, s-electrons display ferromagnetic properties and insulator-to-metal transition depending on the loading density of alkali metals. These properties vary widely with the kind of alkali metals and the structure type of zeolites as well. A huge spin-orbit interaction is observed in the degenerate orbitals of clusters due to the lack of inversion symmetry at the internal surface of clusters. These novel properties can be understood systematically through this research.
