摘要: 采用LLP变分法研究了三角量子阱中束缚磁极化子的性质.在不同库伦束缚势下,得到了基态能、基态结合能与磁场回旋频率及电子面密度之间的关系. 数值计算结果表明: 基态能量随着电子面密度和磁场回旋频率的增加而增加,基态结合能随着电子面密度和磁场回旋频率的增加而减少.Abstract: The properties of the bound magnetopolaron in a triangular quantum well were investigated within Lee-Low-Pines(LLP) variational method. At different Coulomb bound potentials, the ground state energy and the ground state binding energy were obtained as functions of the cyclotron resonance frequency of magnetic field and the electron areal density. The results showed that the ground state energy was found to increase with the electron areal density and the cyclotron resonance frequency of the magnetic field, whereas the ground state binding energy was found to decrease with them.
