This course describes advancements in spectroscopic-imaging scanning tunneling microscopy. Various emergent phenomena in condensed matter, such as superconductivity and magnetism, are governed by many interacting electrons. Therefore, electron spectroscopy techniques are indispensable to elucidate the electronic states behind the emergent phenomena. Spectroscopic-imaging scanning tunneling microscopy is a powerful tool for electron spectroscopy that possesses atomic spatial resolution and sub-meV energy resolution, being juxtaposed with angle-resolved photoemission spectroscopy. Moreover, spectroscopic-imaging scanning tunneling microscopy works under extreme conditions of ultra-low temperature and high magnetic field, enabling us to explore novel emergent phenomena. I will start with basic principles and technical aspects of the technique, followed by applications to high-temperature superconductors and topological quantum phenomena.
Understanding the basic principles and data analyses of spectroscopic-imaging scanning tunneling microscopy.
Obtaining knowledge of application examples of spectroscopic-imaging scanning tunneling microscopy.
spectroscopic-imaging scanning tunneling microscopy, measurements under extreme conditions, superconductivity, topological quantum phenomena.
