由分数维的尺寸方法,在圆柱的 GaAs/Al x Ga 1x 作为核心壳, nanowire 被探索。在这研究,极化子在 GaAs/Al x Ga 1x 作为在壳的不同价值的核心壳 nanowire,宽度和铝集中被讨论。极化子绑定精力,极化子团移动和分数维的尺寸参数数字地作为核心半径的一个函数各被得出。计算结果证明当核心半径增加,有约束力的精力和极化子的集体移动首先增加然后减少,形成他们为在给定的壳宽度的不同的铝集中的相应最大的价值。在圆柱的 GaAs/Al x Ga 1x 作为核心壳, nanowire 被使用分数维的尺寸方法避免复杂、过长的计算简单地解决。
By the fractal dimension method, the polaron properties in cylindrical GaAs/AlxGa1-xAs core-shell nanowire are explored. In this study, the polaron effects in GaAs/AlxGa1-xAs core-shell nanowire at different values of shell width and aluminum concentration are discussed. The polaron binding energy, polaron mass shift and fractal dimension parameter are numerically worked out each as a function of core radius. The calculation results show that the binding energy and mass shift of the polaron first increase and then decrease as the core radius increases, forming their corresponding maximum values for different aluminum concentrations at a given shell width. Polaron problems in the cylindrical GaAs/AlxGa1-xAs core-shell nanowire are solved simply by using the fractal dimension method to avoid complex and lengthy calculations.
