Researchers in the US say that they have made the best 3D topological insulator to date – that is, a material completely insulating in the bulk but conducting at its surface. The structure, made from bismuth antimony tellurium selenide (BiSbTeSe2) might not only be of fundamental importance for testing out a number of condensed matter and particle physics theories but might also be exploited in spintronics applications, and even to build topological qubits for “fault tolerant” quantum computers of the future…..
