摘要
在Kronig-Penney模型的框架内,考虑势垒和势阱中电子有效质量的差异及表面势垒的起伏,研究了半限量子阱超晶格中的度子表面态。同时,对AsGa/AlGa_(1-x)As量子阱超晶格在不同掺杂浓电x下的表面态进行了数值讨算并作了讨论。
The electronic surface states in semi-infinite quatum-well superlattice has been been studied within the framework of Kroning-Penny modlel. The difference of the effective mass between the barrier and well is considered.
