Femtosecond energy relaxation in suspended graphene : phonon-assisted spreading of quasiparticle distribution
Ultra-fast optical measurements of few-layer suspended graphene films grown by chemical vapor deposition were performed with femtosecond pump–probe spectroscopy. The relaxation processes were monitored in transient differential transmission (ΔT/T) after excitation at two different wavelengths of 350...
