Abstract The role of the nature of confinement on a neutral hydrogenic donor impurity in a quantum dot is studied using a power-exponential potential in the presence of Rashba and Dresselhaus spin-orbit interactions and an external magnetic field. The ground state energy is calculated variationally and the corresponding binding energy, magnetic moment and susceptibility are obtained as a function of various quantum dot parameters.

磁场中具有自旋轨道耦合的 GaAs 量子点中 D0 杂质的约束形状效应

摘要 在存在 Rashba 和 Dresselhaus 自旋轨道相互作用和外部磁场的情况下，使用幂指数势研究了限制性质对量子点中的中性氢供体杂质的作用。基态能量是可变计算的，相应的结合能、磁矩和磁化率是各种量子点参数的函数。
