This paper reviews the background of modulation spectroscopy, particularly electromodulation, presents some recent room temperature results having both fundamental and technological significance, including two-dimen­sional electron gas effects in modulation-doped, pseudomorphic GaAlAs/InGaAs/GaAs single quantum wells (HΕΜΤ structures), quantum well laser structures and process-induced damage in quantum dot arrays fabricated by reactive ion etching.
