Abstract
Far-IR electroluminescence is investigated in quantum cascade structures. Narrow luminescence peak with a full- width at half maximum of 0.7 meV are measured at low excitation currents and low temperature. The temperature dependence of the luminescence efficiency is studied systematically up to 120K, showing the interplay between electron-electron and optical phonon emission. Electroluminescence is also studied in a structure based on a diagonal transition and compared with the magnetotransport data. Wider luminescence peaks and intrinsic instabilities are observed.
