  The collective oscillations of surface charges (surface plasmons) induced by
light-matter interactions were predicted in the 1950s to influence electrical
conduction in 2D noble metals. Primarily two mechanisms were predicted and
later by Frohlich which could affect the electron transport in metals; (1)
Umklapp electron-electron scattering and (2) attractive interaction between
free electrons in transition metals because of screening of the d-band
electrons by the s-band electrons. [1] However, there is no experimental
evidence to date on how such oscillations might influence the electrical
conductivity of 2D metals. We have conducted in-situ measurements of the
surface plasmons and electrical resistivity of thin film gold. We observe
striking correlations between the electrical resistivity of noble metal thin
films and surface plasmon resonance
