附注	geometrically anisotropic gasb/gaas quantum dots (qds) that are elongated along the [110] direction are embedded in the vicinity of a modulation-doped algaas/gaas heterointerface. at 4.2 k, the electron mobilities mu(parallel to) and mu(perpendicular to), which are parallel and perpendicular to the qd elongation axis, respectively, are systematically investigated as a function of the electron concentration ns by both experimental measurements and theoretical simulations. in the experiments, the mobility ratio mu(parallel to)/mu(perpendicular to) increased with increasing ns. the mobility anisotropy, attributed to the anisotropic scattering potential of the elongated gasb qds, is calculated under the theoretical model of a rectangular scattering potential of gasb qds.
