Abstract

We report two aspects of holes in GaAs-AlGaAs multiple quantum wells, namely the energy band structure and excitonic effects. The valence band structure is studied by cyclotron resonance of two-dimensional holes at high magnetic fields. The heavy hole cyclotron mass strongly depends upon the well size and magnetic field. This behavior is explained by the valence band Hamiltonian. We also discuss the exciton state in a hole plasma. Experimental evidence for the exciton stabilization by magnetic fields is presented.
