The experimental band structure of Mo(112) and the effects by temperature and adsorbate were presented. A surface resonance, identified as crossing the Fermi level at about 1/3 from the surface Brillouin zone, was observed to be very sensitive to both contamination and temperature. Evidence was found for adsorbate and temperature induced reconstruction of the Mo(112) surface. Examination of low-energy electron diffraction and scanning tunnelling microscopy data provides evidence for an adsorbate induced reconstruction of the Mo(112) surface with periodicities consistent with the Fermi level crossing of the surface resonance. The reconstruction was found to occur at coverages as low as 0.03 Langmuirs of oxygen or carbon. The reconstruction and/or adsorbate affects the density of states and bands near the Fermi level of a1 symmetry.
