Abstract
Synchrotron radiation angle-resolved photoemission spectroscopy of Bi(111) shows that the Fermi surface consists of six elongated hole pockets along the directions surrounding a ring-shaped electron pocket centered at , all of which have two-dimensional character. The associated hole and electron sheet densities are and , respectively. A weak emission feature associated with the bulk hole pocket in the Fermi surface was identified. The Fermi momentum of the bulk hole band near the point is .
