摘要
在双抛量子阱(Double Parabolic Quantum Well)中令势垒厚L_b=0,可得到类似"δ"势结构,在此基础上计算了"δ"势阱中的电子能级和类氢杂质的结合能,分析了"δ"垫垒的变化对能量和结合能的影响。
A quasi-'δ' potential structure is formed when the barrier width (L_b) comes to zero in a double parabolic quantum-well. The energy levels of an electron and the binding energy of a hydrogenic impurity in quasi-'δ' potential-wells is investigated. The effects of the barrier on energy levels and the binding energy is also studied.
