三维（3D）拓扑绝缘体代表了一类新的材料，其中输运由狄拉克表面态控制，而本体保持绝缘。由于表面态的螺旋自旋极化，3D拓扑绝缘体与附近超导体的耦合有望产生非常规的邻近诱导p波超导性。我们在这里报告的发展和测量的超导量子干涉装置的表面上的应变碲化汞，三维拓扑绝缘体，作为一个潜在的工具来调查这种效果。
Three-dimensional (3D) topological insulators represent a new class of materials in which transport is governed by Dirac surface states while the bulk remains insulating. Due to helical spin polarization of the surface states, the coupling of a 3D topological insulator to a nearby superconductor is expected to generate unconventional proximity induced p-wave superconductivity. We report here on the development and measurements of superconducting quantum interference devices on the surface of strained HgTe, a 3D topological insulator, as a potential tool to investigate this effect.
