Two dimensional magnetophonon resonance in GaInAs-InP and GaInAs- AlInAs heterojunctions and superlattices.
01 January 1984
We report the observation of magnetophonon resonance in GaInAs- InP heterojunctions and measurements of the temperature dependence of the oscillations. A single series of oscillations due to scattering by the "GaAs-like" mode of GaInAs is seen, in contrast to GaInAs-InP superlattices, where scattering from InP phonons is also observed, and GaInAs-AlInAs heterojunctions, where coupling to "InAs-like" modes only is seen: This behavior is discussed in terms of long-range phonon interactions and interface phonons.
