Research Abstract

The aim of our research was to clarify the spin-split band structures of nanostructures induced by a space inversion symmetry utilizing spin-and angle-resolved photoemission spectroscopy, high-resolution angle-resolved photoemission spectroscopy and scanning tunneling microscopy. In the study, spin polarized bulk continuum states in a Bi single crystal, a giant spin-split bands at Tl and Pd adsorbed semiconductor surface and new topological insulators have been discovered.
