Precision Control of Amphoteric Doping in Cu _x Bi₂Se₃ Nanoplates.

ABSTRACT: Copper-doped Bi₂Se₃ (Cu _x Bi₂Se₃) is of considerable interest for tailoring its electronic properties and inducing exotic charge correlations while retaining the unique Dirac surface states. However, the copper dopants in Cu _x Bi₂Se₃ display complex electronic behaviors and may function as either electron donors or acceptors depending on their concentration and atomic sites within the Bi₂Se₃ crystal lattice. Thus, a precise understanding and control of the doping concentration and sites is of both fundamental and practical significance. Herein, we report a solution-based one-pot synthesis of Cu _x Bi₂Se₃ nanoplates with systemati
