Description:
Author(s): Cynthia Aku-Leh, Klaus Reimann, Michael Woerner, Eva Monroy, and Daniel Hofstetter Spectrally resolved femtosecond pump-probe measurements of intersubband transitions in a strongly polar GaN/AlN superlattice are presented. A Fourier transform of the data reveals backfolded longitudinal acoustic phonons. The observed phonons couple strongly to the intersubband transitions and modul... [Phys. Rev.
