Abstract :
We present experimental data on the temperature dependence of photo-hole decay obtained by Angle Resolved Photoemission (ARPES) measurements from 4d derived Quantum Well States (QWS) on Ag(111) monolayer films deposited on Pd(111), Ni(111), Mo(110) and Cu(100). We have found a significant increase of the Ag 4d electron–phonon (e-ph) coupling strength with respect to the bulk values. The increase is attributed to different mechanisms that are associated with the interaction of the Ag film with under laying substrate. It is proposed that the main channels that contribute to the increased e-ph coupling originate from the inter-band transitions that involve bulk states of the substrates.
