Band dispersion of localized valence states in LiF(100)
- 1. IBM Research Division, Thomas J. Watson Research Center, P.O. Box 218, Yorktown Heights, New York 10598 (United States)
Description
The band dispersion of the localized, F 2p-like valence band of LiF is mapped using an imaging technique to obtain k(E). The bandwidth is 3.5 eV (from Γ15 to X4'). This is 17% wider than predicted by first-principles band calculations, implying an expansion of the bandwidth by self-energy effects in qualitative agreement with quasiparticle calculations. The self-energy effect is opposite to that seen in delocalized systems, such as alkali metals
