不同生长取向的Bi1-xSbx薄膜的Phase Diagrams

Phase Diagrams of Bi1-xSbx Thin Films with Different Growth Orientations

Shuang Tang, Mildred S. Dresselhaus

摘要:

建立了一个计算二维非抛物载流子袋量子限制引起的带边位移的封闭模型。在此基础上,计算了沿不同晶轴生长的BiSb薄膜的对称性和载流子袋的能带位移。计算并分析了不同生长取向的BiSb薄膜体系的相图。

英文摘要:

A closed-form model is developed to evaluate the band-edge shift caused by quantum confinement for a two-dimensional non-parabolic carrier-pocket. Based on this model, the symmetries and the band-shifts of different carrier-pockets are evaluated for BiSb thin films that are grown along different crystalline axes. The phase diagrams for the BiSb thin film systems with different growth orientations are calculated and analyzed.
