Terahertz intersubband emission in strong magnetic fields
Stéphane Blaser, Michel Rochat, Mattias Beck, Daniel Hofstetter & Jérôme Faist
| Résumé |
Electroluminescence in quantum-cascade structures based on vertical
transitions is studied in a strong perpendicular magnetic field in
the limit in which the cyclotron energy is larger than the
intersubband transition energy. Cyclotron emission and a
luminescence intensity enhancement up to a factor of 6 is observed
in GaAs/AlGaAs and InGaAs/InAlAs vertical transition-based
quantum-cascade structures. (C) 2002 American Institute of
