The electronic structure of the diamond C(100)‐(2×1)/(2×2) has been investigated by means of angle‐resolved photoelectron spectroscopy for the first time. A surface‐related shift has been observed in the C 1s core‐level spectrum. The surface‐state band dispersion was measured along the symmetry axis Γ–J’ in the surface Brillouin zone. For k∥=0, there is a very pronounced surface state 1.5 eV below Fermi level EF , and it disperses downwards with increasing k∥. Near the boundary of the surface Brillouin zone J’, we find two states with binding energies of 1.9 and 2.4 eV with respect to EF .
