中文摘要 | the electronic structure, zeeman splitting, and g factor of mn-doped cds nanowires are studied using the k center dot p method and the mean field model. it is found that the zeeman splittings of the hole ground states can be highly anisotropic, and so can their g factors. the hole ground states vary a lot with the radius. for thin wire, g(z) (g factor when b is along the z direction or the wire direction) is a little smaller than g(x). for thick wire, g(z) is mcuh larger than g(x) at small magnetic field, and the anisotropic factor g(z)/g(x) decreases as b increases. a small transverse electric field can change the zeeman splitting dramatically, so tune the g(x) from nearly 0 to 70, in thick wire. the anisotropic factor decreases rapidly as the electric field increases. on the other hand, the zeeman splittings of the electron ground states are always isotropic. |
