Abstract

Ultrafast charge carrier dynamics in graphite are investigated by time-resolved THz spectroscopy. Our data show that (i) more than 90 % of the initially deposited excitation energy is transferred to few strongly coupled lattice vibrations within 500 fs and (ii) these optical phonons substantially contribute to the striking increase of the Drude relaxation rate.
