    Materials Design for Topological Electronics
    Topological electronics is a new field of interest utilizing the topologically distinctive state of matters. For topological electronics, where the information is carried by the topological charge through the topological domain boundary, at least two distinctive topological phases should be accessible and controllable in one system. By using the relativistic ab-initio first-principles calculation, we are trying to find a candidate platform to host versatile topological phases and control the topological domain boundary through which the topological charges flow.
