With the use of angle-resolved photoemission with synchrotron radiation, surface states on the (2×1)/(2×2) reconstructed diamond (111) surface are characterized. These states cover an energy range of about 2 eV and exhibit maximum emission intensity at 1 eV below the valence-band maximum in normal emission (i.e., at the center » of the surface Brillouin zone). The symmetry is determined to be 1(s,pz-like) by using polarization selection rules. For off-normal emission an upwards energy dispersion by about 1 eV is seen. This behavior is similar to the energy position, dispersion, and symmetry of surface states on the Si(111)-(2×1) cleavage plane and in contrast with the momentum distribution of the band of graphite which is peaked at the boundary of the surface Brillouin zone. © 1981 The American Physical Society.
