Magnetophonon Resonance and Remote Phonon Scattering in a GaInAs- AlInAs Multi-Quantum Well.
01 January 1989
Magnetophonon measurements in a GaInAs/AlInAs multi-quantum well show evidence for a remote phonon interaction with AlAs- like phonons in the barriers. The strongest oscillations come from absorption of GaAs-like L.O. phonons in the wells in the contrast to earlier results for high carrier density heterojunctions.
