Topological insulator nanostructures and devices

Topological insulators' properties and their potential device applications are reviewed. We also explain why topological insulator (TI) nanostructures are an important avenue for research and discuss some methods by which TI nanostructures are produced and characterized. The rapid development of high-quality TI nanostructures provides an ideal platform to exploit salient physical phenomena that have been theoretically predicted but not yet experimentally realized.
