Energy band mapping of silver (110)‎ by angle resolved photoemission

الملخص EN

Angle-resolved photoemission spectra using synchrotron radiation are reported in the energy range 10 £ hv ^ 34 eV for Ag (110).

Empirical dispersion relations are derived using a free-electron-like final state with parameters determined from previous energy coincidence measurements.

The resulting initial state bands are in good agreement with theoretical band structure calculations, except for the lowest energy states, where the calculated energies appear to be low by as much as 0.4 eV.

The validity of the free-electron model is examined in detail and found to be entirely consistent with all experimental results.
