Zusammenfassung

Interband absorption in ultra-thin strained MBE-grown epilayers of ZnTe and ZnSe has been measured in magnetic fields up to 6 T. The spectra simultaneously uncover two effects of the magnetic field: diamagnetic shifts of exciton states, and the rich oscillatory structure arising from formation of Landau levels in the continuum. The observed spectral features are analyzed using the 8 × 8 k·p ...
