Photoluminescence Spectra of GaAs Quantum Wires in High Magnetic Fields
We investigated the photoluminescence (PL) spectra of GaAs quantum wires in high magnetic fields up to 40 T. The observed PL peak shift of the quantum wires with the increase of the applied magnetic field was much smaller than that of the bulk. In addition, it was found that the PL peak shift of the quantum wires was strongly dependent on the direction of the magnetic field. These results demonstrate the existence of the two-dimensional confinement effect in quantum wires.
