Abstract

Abstract Angular resolved photoelectron spectra are presented for the narrow-gap semiconductor PbS. Two different photon energies and two different azimuthal orientations of the (100) surface are employed. The experimental results provide a further test for the validity of the one-dimensional density of states approach in the case of the lead chalcogenides. The experimental binding energies of 10 three-dimensional critical points are compared with the prediction of two independent band structure calculations.
