Crystal structureRamanAnnealingIn this study, we investigated the growth, morphology and crystal structure of electrodeposited Bi2Se3 films on n-Si, Au and Ru substrates. The range of potentials at which films with good quality and stoichiometry can be grown have been identified. Scanning electron ...

8.1 in the case of Bi2Se3 [11]. It has a trigonal axis (threefold rotational symmetry), defined as the z-axis, a binary axis (twofold rotational symmetry); defined as the x-axis, a bisectrix axis (in the reflection plane); and defined as the y-axis. Each Bi2Se3 layer consists ...
(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...

The results of X-ray diffraction and High-resolution transmission electron microscopy showed that the as-obtained bulk Bi 2 Se 3 crystal has layered structure with (0 0 L) planes being aligned along one direction. Both the measurement of component and the electrical transport showed that the ...
BSTS has the tetradymite structure consisting of the stacked Te(Se)1-Bi(Sb)1-Te(Se)2-Bi(Sb)1-Te(Se)1. Since Se atom has more electronegativity tuhnaint, Te atom, the Se atom tends to occupy the central layer in BSTS structure unit20. The almost unity of Se2 occupancy (and much...
