Electron phonon coupling in ultrathin Pb films on Si(111): Where the heck is the energy?
M. Tajik, T. Witte, Ch. Brand +4
In this work, we study the heat transfer from electron to phonon system within a five monolayer thin epitaxial Pb film on Si(111) upon fs-laser excitation. The response of the elec…
