Magnetic Quantum Oscillations in the Auger Transition Rate
1976
The first observation of magnetic quantum effects in Auger recombination is reported. Experiments were carried out with the semiconducting compounds ${\mathrm{Hg}}_{1\ensuremath{-}x}{\mathrm{Cd}}_{x}\mathrm{Te}$. In addition to significant oscillations, the lifetime increases strongly with the magnetic field, as a result of the magnetic-field-induced spin polarization. The effect provides a very sensitive method for the determination of band parameters and may give valuable information on the electron-electron interaction in magnetic fields.
