Electroreflectance Studies of Symmetrically Coupled GaAs/AlGaAs Double Quantum Wells
並列摘要
Electroreflectance (ER) spectroscopy has been used to study two GaAs/AlGaAs symmetrically coupled double quantum wells (CDQW s) with different barrier widths as a function of various externally applied electric fields. The value of the internal field was directly evaluated from the Franz-Keldysh oscillations observed in the spectra of the AlGaAs barrier material. By comparing the ER spectra taken at the fundamental modulation frequency (If), second harmonic frequency and derivative of If spectrum, the features associated with red shift and blue shift were identified unambiguously. The shifts of the coupled quantum confined levels are in good agreement with a theoretical calculation based on solving the numerical solution of the effective-mass Schrodinger equation using the Runge-Kutta method.
