Chemical potential dependent gap-opening at the Dirac surface states of Bi2Se3 induced by aggregated substitutional Cr atoms
Cui-Zu Chang, Peizhe Tang, Yi-Lin Wang +11
With angle-resolved photoemission spectroscopy, gap-opening is resolved at up to room temperature in the Dirac surface states of molecular beam epitaxy grown Cr-doped Bi2Se3 topolo…

Stable two-dimensional dumbbell stanene: a quantum spin Hall insulator
Peizhe Tang, Pengcheng Chen, Wendong Cao +7
We predict from first-principles calculations a novel structure of stanene with dumbbell units (DB), and show that it is a two-dimensional topological insulator with inverted band…
