Ultrafast terahertz conductivity in epitaxial graphene nanoribbons: an interplay between photoexcited and secondary hot carriers
Arvind Singh, Hynek NÄmec, Jan Kunc +1
Optical pump-terahertz probe spectroscopy has been used to investigate ultrafast photo-induced charge carrier transport in 3.4 m wide graphene ribbons upon scaling the optical…
