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…
Stacking Order Driven Optical Properties and Carrier Dynamics in ReS2
Yongjian Zhou, Nikhilesh Maity, Amritesh Rai +8
Two distinct stacking orders in ReS2 are identified without ambiguity and their influence on vibrational, optical properties and carrier dynamics are investigated. With atomic reso…
Phonon-Phonon Quantum Coherent Coupling in GaAs/AlAs Superlattice
Feng He, Nathanial Sheehan, Seth R Bank +2
Quantum coherent coupling between a zone-center phonon and two acoustic phonons was observed in two GaAs/AlAs superlattices (8 nm/8 nm and 5.4 nm/5.4 nm) at ambient temperature. Us…
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…
Synthesis of clathrate cerium superhydride CeH9 below 100 GPa with atomic hydrogen sublattice
Nilesh P. Salke, M. Mahdi Davari Esfahani, Youjun Zhang +7
Hydrogen-rich superhydrides are believed to be very promising high-Tc superconductors as they are expected to mimic characteristics of metallic hydrogen. Recent experiments discove…
Accelerated Carrier Recombination by Grain Boundary/Edge Defects in MBE Grown Transition Metal Dichalcogenides
Ke Chen, Anupam Roy, Amritesh Rai +5
Defect-carrier interaction in transition metal dichalcogenides (TMDs) play important roles in carrier relaxation dynamics and carrier transport, which determines the performance of…
