Abstract

Owing to its high carrier mobility and weak interaction with phonons, graphene demonstrates remarkable carrier dynamics in the terahertz (THz) range. Our recent experimental results for the active spatial control of graphene plasmons and ultrafast optical-to-electrical conversion processes in graphene photodetectors are presented herein, in addition to an explanation of the on-chip THz spectroscopy method developed for the time-domain measurement of ultrafast electrical currents excited at the photodetector.
