| Abstract: | The last several years have witnessed the rapid developments in the study and understanding of topological insulators.In this review,after a brief summary of the history of topological insulators,we focus on the recent progress made in transport experiments on topological insulator films and nanowires.Some quantum phenomena,including the weak antilocalization,the Aharonov-Bohm effect,and the Shubnikov-de Haas oscillations,observed in these nanostructures are described.In addition,the electronic transport evidence of the superconducting proximity effect as well as an anomalous resistance enhancement in topological insulator/superconductor hybrid structures is included. |
