- Abstract
An rf modulation optical spectroscopy method for the study of semiconductor heterostructures is suggested which employs the effect of the light reflection coefficient modulation under the action of two rf fields with different configurations. The dependence of the rf-modulated light reflection spectra at the fundamental absorption edge of a semiconductor on the rf field polarization allows various layers of the heterostructure to be selectively studied. A model is proposed that explains the features observed in the reflection spectra of the light modulated by longitudinal and transverse rf electric fields in a GaAs/AlGaAs heterostructure.
