The authors have applied resonant Raman spectroscopy to two p-type modulation-doped GaAs-GaAlAs multiple-quantum wells (MQW) with well widths dW=10 and 30 nm. In both samples one of the hole intersubband transitions observed is coupling to the quantum-well LO (longitudinal optical) phonon. The influence of an external magnetic field on this coupling phenomenon was investigated. A shift of the ...
