Time-resolved terahertz dynamics in thin films of the topological insulator BiSe
R. Valdés Aguilar, J. Qi, M. Brahlek +7
We use optical pump--THz probe spectroscopy at low temperatures to study the hot carrier response in thin BiSe films of several thicknesses, allowing us to separate the bul…

Near-bandgap wavelength-dependent studies of long-lived traveling coherent longitudinal acoustic phonon oscillations in GaSb/GaAs systems
J. K. Miller, J. Qi, Y. Xu +6
We report first studies of long-lived oscillations in optical pump-probe measurements on GaSb-GaAs heterostructures. The oscillations arise from a photogenerated coherent longitudi…
