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…
Ab initio phonon transport across grain boundaries in graphene using machine learning based on small dataset
Amirreza Hashemi, Ruiqiang Guo, Keivan Esfarjani +1
Establishing the structure-property relationship for grain boundaries (GBs) is critical for developing next generation functional materials, but has been severely hampered due to i…
Machine-learning based interatomic potential for phonon transport in perfect crystalline Si and crystalline Si with vacancies
Hasan Babaei, Ruiqiang Guo, Amirreza Hashemi +1
We report that single interatomic potential, developed using Gaussian regression of density functional theory calculation data, has high accuracy and flexibility to describe phonon…
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,…
Critical role of next-nearest-neighbor interlayer interaction in magnetic behavior of magnetic/nonmagnetic multilayers
Sunjae Chung, Sangyep Lee, Taehee Yoo +9
We report magnetoresistance data in magnetic semiconductor multilayers, which exhibit a clear step-wise behavior as a function of external field. We attribute this highly non-trivi…
