Paper Abstract

We review recent work on the scattering of electrons in doped quantum wells in high magnetic fields. Picosecond time-resolved far-IR measurements have allowed the determination of scattering lifetime between Landau levels as a function of applied field in quantum wells and bulk material. The measurements show a clearer suppression of the cooling rate when the Landau level spacing is equal to the phonon energy, and thus the results provide unambiguous evidence for the phonon bottleneck.
