Femtosecond carrier dynamics in photoexcited highly ordered pyrolytic graphite films
Source abstract
Abstract
Abstract The ultrafast relaxation of photoexcited carriers in thin films of exfoliated highly ordered pyrolytic graphite are examined using the equal-pulse correlation technique. An extremely fast relaxation due to intraband carrier–carrier thermalization was observed at 15 ± 10 fs followed by intraband carrier–optical phonon interaction on the order of 175 ± 30 fs. A modulation in the absorption depth of 1.4% was observed in the samples from partial saturation due to Pauli blocking.
