Transient Hydrodynamic Lattice Cooling by Picosecond Laser Irradiation of Graphite
Jihoon Jeong, Xun Li, Sangyeop Lee +2
Recent theories and experiments have suggested hydrodynamic phonon transport features in graphite at unusually high temperatures. Here, we report a pico-second pump-probe thermal r…
Hydrodynamic Phonon Transport: Past, Present, and Prospect
Sangyeop Lee, Xun Li
The hydrodynamic phonon transport was studied several decades ago for verifying the quantum theory of lattice thermal transport. Recent prediction of significant hydrodynamic phono…
Thermal resistance by transition between collective and non-collective phonon flows in graphitic materials
Sangyeop Lee, Xun Li, Ruitiang Guo
Phonons in graphitic materials exhibit strong normal scattering (N-scattering) compared to umklapp scattering (U-scattering). The strong N-scattering cause collective phonon flow,…
Crossover of ballistic, hydrodynamic, and diffusive phonon transport in suspended graphene
Xun Li, Sangyeop Lee
Hydrodynamic phonon transport was recently predicted as an important regime for phonon transport in graphitic materials. Many of past studies on hydrodynamic phonon transport have…
