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…
