Weak antilocalization and electron-electron interaction in coupled multiple-channel transport in a Bi${}_2$Se${}_3$ thin film

Yumei Jing, Shaoyun Huang, Kai Zhang +5

Electron transport properties of a topological insulator Bi${}_2$Se${}_3$ thin film are studied in Hall-bar geometry. The film with a thickness of 10 nm is grown by van der Waals epita…
