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…

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…
