We present results from measurements of ultrafast thermal transport in Graphene. We find that on picosecond time scales and 5-20 micron length scales hot carriers, instead of the phonons, are the dominant carriers of thermal energy. The thermal transport is found to be diffusive with a diffusivity of ~500 cm2/s.
We have investigated the THz emission from lithium ternary chalcopyrite crystals illuminated femtosecond pump laser pulses. THz emission from the coherent phonon in LiInSe2 and LiGaSe2 are observed at 2.87 and 3.45 THz respectively.
In contrast to the previously-studied coherent phonons excited through high-energy (E22) transitions, the redial breathing modes show comparable intensities between v = +1 and −1 nanotubes.
