摘要：

Magnetophotoluminescence spectra of GaAs quantum wires with lateral and vertical dimensions of 20 and 10 nm, respectively, were measured up to 40 T with three orthogonal magnetic field configurations. The observed photoluminescence peak shift with increase of applied magnetic field was strongly dependent on the direction of magnetic field, which directly demonstrates the existence of two-dimensional confinement in the quantum wires. It was found that the excitons were anisotropically shrunk in the quantum wires, and that the observed magnetic energy shift was consistent with the size of the quantum wire structure.
