中文摘要	the electronic structure, electron and hole g factors and optical properties of cdte quantum ellipsoids are investigated, in the framework of eight-band effective-mass approximation. it is found that the light-hole states come down in comparison with the heavy-hole states when the spheres are elongated, and become the lowest states of valence band. when the aspect ratio of the ellipsoid length to diameter (e) changes from smaller than 1 to larger than 1, the linear polarization factors change from negative to positive. the electron g factors of cdte spheres decrease with increasing radius, and are nearly 2 when the radius is very small. actually, as some of the three dimensions increase, the electron g factors decrease. more dimensions increase, the g factors decrease. more. the dimensions perpendicular to the direction of the magnetic field affect the g factors more than the other dimension. the light-hole and heavy-hole g factors of quantum spheres are equal, and change from 0.88 to -1.14 with increasing radius. when e < 1 (e > 1) the light-hole g factor is smaller (larger) than the heavy-hole g factor.
