Abstract:
The basic features of the band structure observed in bulk samples are retained in polycrystalline SmS thin films. Specifically, the bottom of the conduction band is formed from $s$-type states and there exist donor impurity levels in the band gap, at an energy of 0.04–0.065 eV below the bottom of the conduction band.
Keywords:
polycrystalline samarium-sulfide films, far- and mid-IR regions, band structure.
