非对称Gaussian限制势量子阱中强耦合极化子的基态能量
|
摘要
应用线性组合算符和幺正变换方法从理论上研究了非对称Gaussian限制势CsI半导体量子阱中强耦合极化子基态能量的性质,仔细地分析了非对称Gaussian限制势量子阱中强耦合极化子的基态能量与非对称Gaussian受限势量子阱的势垒高度和非对称Gaussian受限势的范围的依赖关系.通过数值计算结果发现,量子阱中强耦合极化子的基态能量的绝对值是非对称Gaussian受限势量子阱的势垒高度和非对称Gaussian受限势的范围的增函数.
The properties of the ground state energy of the strong-coupling polaron in an asymmetrical Gaussian confinement potential CsI semiconductor quantum well were theoretically studied by using the linear combination operator and unitary transformation methods. The influences of the barrier height of the quantum well and the range of the Gaussian confinement potential on the polaron's ground state energy are analyzed. The numerical results found that the absolute value of the ground state energy of strong-coupling polaron is an increasing function of the range of the Gaussian confinement potential and the barrier height of the quantum well.
