Plasmon extinguishment by bandedge shift identified as a second-order spectroscopic differentiation
Optical excitation of metallic nanostructures induces strong intraband transitions, leaving transient depletion below the Fermi level, which allows transient interband transition to this depletion band. This is equivalent to the lowering of the threshold for interband transitions and pushes the plas...
