Outline of Final Research Achievements |
Topological insulator (TI) is a new class of quantum material, which cannot be simply classified neither metal, insulator, nor superconductor. TIs have been acquiring considerable attention in broad fields ranging from material science, condensed matter physics, high energy physics, and mathematics, after the theoretical prediction of its existence. Beyond previously known topological insulators, a new class of topological insulator called topological crystalline insulators (TCIs) provide exciting platform for exploring extraordinarily tunability of topologically protected Dirac electron. In this study, using spectroscopic scanning tunneling microscope, we clarified characteristic electronic states of TCI at the atomic scale.
