Surface Resonances on the (100) Plane of Molybdenum

Surface resonances on Mo(100) have been confirmed and studied in detail experimentally by field-emission energy distributions and theoretically by a linear-combination-of-atomic-orbitals calculation of the ${\overrightarrow{\mathrm{k}}}_{\parallel }$-resolved surface local density of states. The experimental results in conjunction with the calculations have provided evidence of band-structure effects in field-emission energy distributions. The calculated results have also explained the angle-resolved photoemission results on W(100) and provided a clear picture as to the origin of these resonances.
