Highlights

• Growth of Bi₂Se₃ microcrystals by physical vapor transport from self-vapor was studied.

• Well-faceted plate-like microcrystals of Bi₂Se₃ up to ∼200 μm in size were grown in sealed ampoules.

• The crystals were verified to have high structural quality by single crystal structure analysis.

• The most probable twin planes in the tetradymite structure were evaluated.

Abstract

High-quality Bi₂Se₃ microcrystals were grown by the physical vapor transport (PVT) method without using a foreign transport agent. The microplate crystals grown under the optimal temperature gradient are well faceted and have dimensions up to ∼200 μm. The growth proceeds by the layer-by-layer mechanism with the formation of flat low-growth rate facets. The phase composition of the grown crystals was identified by the X-ray single crystal structure analysis in space group , a = 4.1356(3), c = 28.634(5) Ǻ, Z = 3 (R = 0.0147). The most probable twin planes in the tetradymite structure were evaluated by the pseudo translational sublattice method.
