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 ∼200μm. 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...
A high quality Bi2Te3 crystal has been grown by Bridgman method with the use of rotating heat field. The phase purity and bulk structural quality of the crystal have been verified by XRD analysis and rocking curve observation. The atomically smooth Bi2Te3(0001) surface with an excellent crystallographic quality is formed by cleavage in the air. The chemical and microstructural properties of the surface...
