Outline of Final Research Achievements |
Quantum confinement of strongly correlated electrons in oxide artificial structures has attracted considerable interest for its potential application in future oxide electronics, and also for providing the opportunity to better understand the fundamental low-dimensional physics of strongly correlated electron systems. In this study, in order to clarify the anomalous behavior of the strongly correlated electrons confined in SrVO3 quantum well (QW) structures, we have investigated their quantized states in terms of in-situ angle resolved photoelectron spectroscopy (ARPES). The detailed analysis of ARPES data has revealed the close relationship between the orbirtal-selective quantization characteristic of the oxide QW and the anomalous quantum phenomena such as subband-dependent mass enhancements. The present study demonstrates that the QW structure of strongly correlated oxide will provide a platform for manipulating novel quantum phenomena in reduced dimensions.
