Samenvatting

Cyclotron resonance is investigated in far-infrared transmission and in photoconductivity measurements on a two-dimensional electron gas in an AlGaAs/GaAs heterojunction. The photoresistivity signal, divided by the temperature coefficient of the resistivity, displayed as a function of magnetic field, reproduces quite well the cyclotron resonance line observed in transmission. There is a slight difference in line width, which may be due to a shorter scattering time for localized as compared to non-localized electrons.
