Fabrication technology of topological superconducting silicide heterostructures

Meeting & Discussion

Through specific semiconductor processes, we grow cobalt disilicide (CoSi2, a kind of superconducting silicides) and titanium disilicide (TiSi2, a kind of non-superconducting silicides with topological band structures) layers to form a hetero-interface on undoped Si(100) substrates. This clean CoSi2/TiSi2 interface allows the charge carriers of the two silicides to easily diffuse into each other, and in turn changes the material properties near the interface to induce unconventional topological superconductivity. Based on this property, submicron devices with two or three terminals can be fabricated for future applications in topological quantum computations.
