Optical studies of carrier and phonon dynamics in Ga_{1-x}Mn_{x}As
K. J. Yee, D. Lee, X. Liu +6
We present a time-resolved optical study of the dynamics of carriers and phonons in Ga_{1-x}Mn_{x}As layers for a series of Mn and hole concentrations. While band filling is the do…
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…
Spin-Landau Orbit Coupling in Units of the Flux Quantum Observed from Zeeman Splitting of a Quantum Wire Array
J. C. Woo, W. S. Kim, H. S. Ko +6
In Zeeman spectra of a GaAs-AlGaAs quantum wire array with superlattice period lp, the zero-field shift is found to increase in steps of (2 pi hbar/ e)lp^{-2} at the cyclotron radi…
