Probing Ultrafast Dynamics of Anharmonically Coupled Phonons in Few-Layer Hexagonal Boron Nitride

Résumé

Nonequilibrium dynamics of transverse optical (TO) phonons in few-layer hexagonal boron nitride is studied in mid-infrared pump-probe experiments. TO phonons display a 1.2 ps lifetime and a transient redshift due to anharmonic coupling with low-frequency interlayer modes.
