| Outline of Final Research Achievements |
Combining spectroscopic imaging scanning tunneling microscopy (STM/STS) with back-gating technique will provide us a great opportunity to visualize electronic evolution across phase transitions at the atomic scale. Particularly interesting system is correlated transition metal oxides, in which rich nanoscale electronic heterogeneity exists. However, the high quality epitaxial thin film surfaces of transition metal oxides are demonstrated little at the atomic level. In this study, we have succeeded to prepare SrVO3(001) film surfaces, on which we clearly see quantum mechanically interfering electronic states. This advancement is the essential step for further development of STM/STS combined with back-gating approach.
