摘 要: 采用提出的等效方法,确定Al_xGa_(1-x)As衬底上GaAs表面薄膜的量子限制长度,在此基础上确定了GaAs薄膜的分数维,进一步利用分数维方法研究了Al_xGa_(1-x)As衬底上GaAs表面薄膜中的极化子特性. Within the framework of fractional-dimensional space approach, the effective length of quantum confinement is determined by an equivalent method. Result of binding energy and effective mass of a polaron confined in a GaAs film deposited on an AlxGa1-x substrate for different aluminum concentration at different values of film thickness have been investigated.
