Ultrabroadband THz Conductivity of Non-equilibrium Dirac Fermions in Graphene

Not Accessible

Your library or personal account may give you access

Abstract

We employ ultrabroadband THz pulses to expose the high-frequency transport of non-equilibrium Dirac fermions in graphene. Tuning the Fermi level reveals a transient response characteristic of high-energy photo-excited carriers with strongly enhanced interactions.
