中文摘要：

采用Pekar变分方法,有外磁场存在的情况下,计算得出了库仑和三角束缚势量子点中电子与体纵光学声子强耦合的条件下的基态能量.以RbCl晶体为例,分别讨论了库仑场、磁场、量子点有效受限长度等因素对三角束缚势量子点的基态能量的影响.

英文摘要：

On the condition of electric-LO phonon strong coupling in Triangular Bound Potential quantum dot , we obtain the energy of ground state by using variational method of Pekar type. Effects of Coulomb Bound Potential, magnetic fields, confinement length and other factors on the ground state energy of RbCl crystal quantum dot was Discussed.
