dc.description.abstract
This study reports on a nonlinear response in thin gold films in the terahertz (THz) frequency region. In an experimental study, the THz-electric peak field strength is increased and the transmission through the gold film is found to increase nonlinearly with the field strength when it exceeds a few hundred kV cm⁻¹. Numerical calculations of the electron dynamics based on the momentum-resolved Boltzmann equation show that the fast ((sub-) picosecond) electron depolarization activates a THz field-induced Pauli blocking nonlinearity of the electron–phonon interaction, resulting in an increased transmission.
