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…
Picosecond Transient Thermoreflectance for Thermal Conductivity Characterization
Jihoon Jeong, Xianghai Meng, Ann Kathryn Rockwell +4
We have developed a transient thermoreflectance technique using picosecond pulsed and cw laser to study thermal conductivity and interface conductance in both thin-films and bulk m…
Comparison between Grating Imaging and Transient Grating Techniques on Measuring Carrier Diffusion in Semiconductor
Ke Chen, Xianghai Meng, Feng He +5
Optical grating technique, where optical gratings are generated via light inference, has been widely used to measure charge carrier and phonon transport in semiconductors. In this…
Optimization of the pulse width and injection time in a double-pass laser amplifier
Daewoong Park, Jihoon Jeong, Tae Jun Yu
We have optimized the input pulse width and injection time to achieve the highest possible output pulse energy in a double-pass laser amplifier. For this purpose, we have extended…
Giant Thermal Conductivity Enhancement in Multilayer MoS2 under Highly Compressive Strain
Xianghai Meng, Tribhuwan Pandey, Suyu Fu +9
Multilayer MoS2 possesses highly anisotropic thermal conductivities along in-plane and cross-plane directions that could hamper heat dissipation in electronics. With about 9% cross…
