Abstract

We have performed resonant Raman spectroscopy on two p-type modulation-doped GaAs---AlGaAs multiple quantum well structures with well widths dW = 10 nm and dW = 30 nm. With the frequency of the dyelaser nearly in resonance with the energy difference between conduction and valence band states of the same subband quantum number n we simultaneously observe Raman intensity of hole intersubband ...
