Figure 1: Defects on a TI surface. Impurity-induced carrier control is the cornerstone of the semiconductor industry, and band structure engineering via disorder is the natural successor of such ...

ARPES maps the electronic properties, including the band structure and Fermi surface, of the topological insulator bismuth selenide (left). Like graphene, the lower energy valence band of a ...

It was the first time researchers have seen this kind of gate-dependent oscillation in nanoribbons and further correlates it to the topological insulator band structure of bismuth telluride. The ...

In 3D time-reversal invariant systems, a topological insulator band structure leads to a strongly correlated topological insulator 26 (TI ∗) that, unlike the TMI described above, exhibits a ...

Theorists and experimenters with Lawrence Berkeley National Laboratory have led in the exploration of the unique properties of topological insulators, where electrons may flow on the surface ...
