Outline of Final Research Achievements |
Recently, metallic quantum well (QW) states in strongly correlated oxide SrVO3 ultra-thin films, where bands derived from d orbitals expanding the surface-normal direction are quantized. In this study, in order to investigate new novel quantum property and make a foundation of material design for development of device and/or supperlattice using the metallic QW sturcture, we have manipulated wave function of the QW states by means of thin-film structure. For the purpose, we have studied the QW states in SrVO3 ultra-thin films and multi-layer structures by angle-resolved photoemission spectroscopy (ARPES). The obtained results indicate that the analysis for the electronic structure using ARPES is a powerful tool for the SrVO3 QW states and the QW states are engineered by means of SrVO3 multi-layer structure.
