The experiment is analyzed in the framework of the improved Wigner-Brillouin perturbation theory taking into account band-coupling phenomena, a finite thickness of the inversion layer in the growth direction, and coupling of the cyclotron transitions due to electron-electron interactions. From the cyclotron mass enhancements, a Fröhlich coupling constant alpha = 0.06 to 0.07 was obtained.enheterostructureHeterostrukturIII-V HalbleiterIII-V semiconductorsquantum wells621667541Influence of the electron-electron and electron-phonon interaction on the cyclotron resonance of 2DEG in GaAsEinfluß der Elektron-Elektronen und Elektron-Phonon Wechselwirkung auf die zyklotron-Resonanz eines 2 DEG in GaAjournal article
