在Bi ${}_{1-x}$ Sb ${}_{x}$薄膜体系中构筑多种Dirac-Cone材料

Constructing a Large Variety of Dirac-Cone Materials in the Bi${}_{1-x}$Sb${}_{x}$ Thin Film System

Shuang Tang, Mildred S. Dresselhaus

摘要:

我们从理论上预测,可以在Bi ${}_{1-x}$ Sb ${}_{x}$薄膜中构建各种Dirac-cone材料,并且我们在这里展示如何构建具有各种波矢各向异性的单Dirac-cone材料、双Dirac-cone材料和三Dirac-cone材料。这些不同类型的狄拉克锥在电子器件设计、量子电动力学和其他领域都有着特殊的意义。

英文摘要:

We theoretically predict that a large variety of Dirac-cone materials can be constructed in Bi${}_{1-x}$Sb${}_{x}$ thin films, and we here show how to construct single-, bi- and tri- Dirac-cone materials with various amounts of wave vector anisotropy. These different types of Dirac cones can be of special interest to electronic devices design, quantum electrodynamics and other fields.
