含类氢杂质的量子点的基态能

The Ground State Energy of a Quantum Dot with Impurity

用Ｐｅｋｅｒ－Ｌａｎｄａｕ变分法计算了含类氢杂质的量子点基态能，发现外磁场、量子点固有禁闭势、电子杂质相互作用、电声子相互作用对量子点基态能都有影响。

The ground state energy of a quantum dot(QD) with a hydrogenic impurity in its center, is studied by Peker landau variational method. It is found that the external magnetic field, the confining potential of QD, the electron impurity interaction and the electron phonon interaction have different effects on the ground state energy of QD, and there are some relations between these effects.
