The topological matters family expands greatly ever since the first observed topological matter, the integer quantum Hall system. Currently, many new types of materials are experimentally available, such as topological insulators (both 2D and 3D), topological crystalline insulators and topological Kondo insulators. In another interesting yet more than 100 years old field, researches in superconductivity keep surprising us with novel materials and phenomena. In this talk, I will briefly review both materials families and present our recent transport experiments on a superconductor-2D topological insulator-superconductor junction. In this hybrid system, giant proximity induced supercurrent is observed in both edge and bulk channels. In addition, the supercurrent can survive in a surprisingly large temperature-magnetic field parameter space. Lastly, I will conclude with an outlook of the field.
