Resumen:
The ordered (100) surface of layered In4Se3 single crystals is characterized by semiconductingquasi-one-dimensional indium In chains. A band with significant dispersion in the plane of thesurface is observed near the valence band maximum. The band exhibits an anisotropic dispersionwith ~1 eV band width along the In chain direction. The dispersion of this band is largely due tothe hybridization of In-s and Se-p orbitals, but the hybridization between In-s and Se-p and In-p and Se-p orbitals is also critical in establishing the band gap.
