Bi2Se3 hexagonal nanodomains structures have been synthesized under the condition of Bi-rich without surfactant. Bi-rich growth condition can result in the forming of quintuple-layer Bi2Se3 nanodomains through forming surface Se vacancy. Bi2Se3 nanodomains structures possess high crystal quality and Se defects without disrupting the host lattice. The forming mechanism of defects is discussed in details. (C) 2013 Elsevier Ltd.
