A study of the phases in the bismuth - tellurium system

Biomolecule-Assisted Hydrothermal Synthesis and Self-Assembly of Bi2Te3 Nanostring-Cluster Hierarchical Structure

“…The lattice parameters from the Rietveld refinement are a ϭ 4.398(1) Å and c ϭ 30.48(1) Å, in good agreement with the standard data of a ϭ 4.395 Å and c ϭ 30.44 Å. 32 The particle sizes were determined by the Scherrer equation through fitting the peaks by a Lorentz function. A silicon standard was used to account for the instrumental broadening.…”

Raman signatures of pressure induced electronic topological and structural transitions in Bi2Te3

“…BT has a layered structure having rhombohedral symmetry ( R3m ) having lattice parameters a = 4.383 Å and c = 30.38 Å (in the hexagonal setting) [16]. being Raman active, where the atoms vibrate in-plane (E g ) and out-of-plane (A 1g ) [17].…”

Growth and characterization of InxBi2−xTe3 single crystals

“…Bi 2 Te 3 has a rhombohedral structure and its hexagonal unit cell is often used in crystal structure studies. Feutelaic et al [10] have reported the values of lattice parameters of the hexagonal cell, as a¼ 4.395Å and c¼30.44Å, in good agreement with our calculated parameters: a¼4.392Å and c¼30.54Å, a¼4.364Å and c¼30.126Å and a¼4.354Å and c¼30.24Å, respectively, for In 0.1 Bi 1.9 Te 3 and In 0.5 Bi 1.5 Te 3 , In 0.2 Bi 1.8 Te 3 and In 0.5 Bi 1.5 Te 3 . The crystals grown as described above were cleaved at 0 1 C for avoiding severe plastic deformation due to mechanical action of cleavage of the crystal.…”
