Constructing a large variety of Dirac-cone materials in the Bi1−xSbx thin film system
Abstract
We theoretically predict that a large variety of Dirac-cone materials can be constructed in Bi1−xSbx 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 device design, quantum electrodynamics and other fields.
