Magnetooptics of a quasizerodimensional electron gas
Abstract
We have investigated theoretically and experimentally the energy levels and allowed optical transitions with energies ΔE of a quasizerodimensional (Q0D) electron gas in a magnetic field B. Using a twodimensional harmonic confining potential with oscillator frequency ω_{0}, the theory predicts two values for ΔE. The resonance position in the magnetotransmission spectra from the Q0D system realized on a gridgate GaAs/AlGaAs heterostructure, depends strongly on the 2D confining potential induced by the gate voltage V_{g} and, when V_{g}=0.5 and 1.5 V, agrees with ΔE calculated with ℏω_{0}=1.5 and 2.8 meV, respectively.
