Abstract: The perpendicular to the chains in the [In.sub.4][Se.sub.3](001) surface is analyzed by a weaker but discernable dispersion perpendicular to both the chain direction and the cleavage plane. A band is identified near the valence band maximum that has fallen into a gap of the projected bulk band structure at the surface Brillouin zone (BZ) edge that might well be a surface state.
