Growth of quantum well films of topological insulator Bi2Se3 on insulating substrate
Cui-Zu Chang, Ke He, Min-Hao Liu +6
Insulating substrates are crucial for electrical transport study and room temperature application of topological insulator films at thickness of only several nanometers. High quali…

Electron interaction-driven insulating ground state in Bi2Se3 topological insulators in the two dimensional limit
Minhao Liu, Cui-Zu Chang, Zuocheng Zhang +10
We report a transport study of ultrathin Bi2Se3 topological insulators with thickness from one quintuple layer to six quintuple layers grown by molecular beam epitaxy. At low tempe…
