The layered In4Se3 system does have a bulk band structure ( i. e. discernable and significant band dispersion) perpendicular to the cleavage plane. Band widths ( the extent of dispersion) of 300 meV or more are observed, for In-p and Se- p weighted bands within the valence region, and is indicative of a bulk band structure. Two-dimensionality of state is clearly not conserved, and there must exist interactions between layers sufficient to support a bulk band structure. (c) 2008 Elsevier B. V. All rights reserved.
