Abstract

The measurement of the linewidths of sp- and d-band derived electronic quantum-well (QW) states in thin films of Ag on Fe(100) as a function of temperature to yield the electron-phonon coupling parameters was presented. It was observed that the electron-phonon coupling parameter for the top d-band quantum-well state, 0.015±0.006, was the smallest. The electron-phonon (e-ph) coupling parameter λ was deduced for several QW states in Ag via a temperature-dependent study. It was found that the sp-band QW peak has a much larger λ than that for the top d-band QW peak.
