(Bi2Te3)x(Sb2Te3)1x solid solutions with x = 0:2, 0.25 and 0.3 p type thermoelectric compounds with an excess of Tellurium dopant up to 4 wt% were crystallized. By increasing the Bi2Te3 content in the Bi-Sb-Te system, the hole concentration decreased and in consequence caused an opt...

i2Te3 crystals29. The value of FWHM is rather low, considering high atomic disorder atomic coordination, Wyckoff and site occupancy of the MBG BSTS obtained from the Rietveld refinement of the powder XRD pattern are analyzed in Table S2. BSTS has the tetradymite structure consisting of the ...
9.1 CRYSTAL STRUCTURE, CRYSTAL LATTICE A crystal is characterized by a three-dimensional, regular, periodic array of particles—atoms and/or molecules. Modern experimental techniques allow us to see the structure of large molecules in crystals using an electron microscope. Figure 9.1 is an electron...
High‐pressure studies of topological insulators Bi2Se3, Bi2Te3, and Sb2Te3 Bi2Se3, Bi2Te3, and Sb2Te3 are narrow bandgap semiconductors with tetradymite crystal structure (R-3m) which have been extensively studied along with their... FJ Manjón,R Vilaplana,O Gomis,... - 《Physica Stat...
Crystal structureWhereas for a series of layered compounds with the general formula (GeTe)n(Sb2Te3)m the stoichiometry allows to predict the structure type and the average thickness of the hexagonal atom layers, these rules are not generally applicable for GeTe-rich compounds like Ge4Sb2Te7. A...
In this letter, we report the crystal structure manipulation of the exchange bias in epitaxial hcp Cr2O3 films. By epitaxially growing twined (1010) oriented Cr2O3 thin films, of which the c axis and spins of the Cr atoms lie in the film plane, we demonstrate that the exchange bias...
