Abstract
Cyclotron resonance is investigated in infrared transmission and in photoconductivity measurements on a 2 DEG in a GaAs/AlGaAs heterojunction. The photoresistivity signal, corrected for the magnetic field dependent sensitivity, shows a narrower (20%) cyclotron resonance linewidth (FWHM) than observed in infrared transmission, indicating a shorter scattering time of the localized as compared to the non-localized electrons. The effective masses as deduced from the positions of the cyclotron resonance are the same within 1% for both types of experiments.
