Ultrafast spectroscopy of propagating coherent acoustic phonons in GaN/InGaN heterostructures
Rongliang Liu, Chang Sub Kim, G. D. Sanders +6
We show that large amplitude, coherent acoustic phonon wavepackets can be generated and detected in InGaN/GaN epilayers and heterostructures in femtosecond pump-probe d…

Exceptionally Slow Rise in Differential Reflectivity Spectra of Excitons in GaN: Effect of Excitation-induced Dephasing
Y. D. Jho, D. S. Kim, A. J. Fischer +4
Femtosecond pump-probe (PP) differential reflectivity spectroscopy (DRS) and four-wave mixing (FWM) experiments were performed simultaneously to study the initial temporal dynamics…
