Abstract:
We describe theoretically the optical properties of ultra-thin Lii-V semiconductor quantum wells and graphene. Specifically, we introduce a new mechanism for the interaction of electrons and optical phonons in III-V semiconductor quantum wells which is mediated via the spin-orbit coupling. We then describe the manifestation of this interaction in the fine structure of the cyclotron resonance near the frequency of the optical phonons in GaAs/AlGaAs heterostructures when the magnetic field is applied perpendicularly to the plane of the two-dimensional electrons. We find that the cyclotron resonance can mix with the transverse optical phonon and that the size of the crossing with this phonon is dependent on the total spin-polarisation of the electron gas.
