Abstract

Cyclotron resonance has been optically detected in a GaAs/Ga0.67Al0.33As superlattice with the wells doped with Si to 6×1016 cm-3. The sign and magnitude of the signal depend on the emission monitored, and an effective mass of 0.062m0 was obtained for the electrons. Because of the low magnetic field needed at 22 GHz for cyclotron resonance, the confinement of the orbits is readily observed. © 1985 The American Physical Society.
