英文: Abstract: We conduct a theoretical study on the properties of a bound polaron in a quantum well under an electric field using linear combination operator and unitary transformation methods,which are valid in the whole range of electron-LO phonon coupling.
中文: 文摘:采用线性组合算符及幺正变换方法研究了电场对量子阱弱耦合束缚极化子的性质的影响.推导出量子阱中束缚极化子的基态能量和库仑束缚势、电场和阱宽的变化关系.数值计算结果表明,基态能量因电场和库仑束缚势的不同而不同,随电场和库仑束缚势的增大而增大,随阱宽的增大而迅速减小.
