WebIn a cube-shaped, strong topological insulator, for example, all six faces can conduct electrons robustly. In a weak TI, only four sides are conducting, while the top and bottom surfaces remain insulating. In a higher-order TI, electrons move only along selected hinges, where two crystal faces intersect.
