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…
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…
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…
Carrier Trapping by Oxygen Impurities in Molybdenum Diselenide
Ke Chen, Anupam Roy, Amritesh Rai +7
Understanding defect effect on carrier dynamics is essential for both fundamental physics and potential applications of transition metal dichalcogenides. Here, the phenomenon of ox…
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…
