SmB6 (IMAGE) Osaka University Caption (a) Crystal structure of SmB6. A shaded area is the (111) surface studied in the current work. (b) Surface electronic structure of SmB6 obtained by angle-resolved photoelectron spectroscopy. Bright area represents the electrons with corresponding wavenumber (Fermi surface). A solid hexagon is the zone boundary determined from surface periodicity.
