Electronic-structure studies of the Nb (110) surface

Abstract
The electronic structure of the Nb (110) surface is studied using angle-resolved photoemission. The properties of the Σ1 band crossing at the Fermi energy are examined in detail. A comparison is made with similar measurements for Mo (110) to evaluate the validity of a rigid-band approximation. The final states along Σ are also studied using synchrotron radiation as a source.
