    <description descriptionType="Abstract">&lt;p&gt;Superlattice structures of (Bi2)m(Bi2Te3)n series with controllable Bi mole fraction from 0.41 to&lt;br&gt;
0.71 are electrodeposited in pulse potentiostatic mode from acidic electrolytes containing Bi(NO3)3 and&lt;br&gt;
TeO2 as precursors. Two valence states of bismuth in superlattices are identified by X-ray photoelectron&lt;br&gt;
spectroscopy (XPS). One of those states is attributed to interlayered Bi0 which is present in&lt;br&gt;
(Bi2)m(Bi2Te3)n superlattice in the form of biatomic layers between bismuth telluride quintuples. X-ray&lt;br&gt;
difraction (XRD) analysis and density functional theory (DFT) calculations indicate an increase in subcell&lt;/p&gt;

&lt;p&gt;parameter asub and decrease in subcell parameter csub with the increase of Bi mole fraction. Biatomic&lt;br&gt;
layers of Bi0 are identified with cyclic voltammetry by characteristic anodic peak between potentials of&lt;br&gt;
metallic bismuth and Bi2Te3 oxidation. The selective oxidation of Bi-bilayers in (Bi2)m(Bi2Te3)n&lt;br&gt;
superlattice at the potential of the anodic peak results in the product corresponding to Bi2Te3 by&lt;br&gt;
stoichiometry, but having an expanded crystal structure. Superlattices with controllable Bi mole fraction&lt;br&gt;
and Bi2Te3 with &amp;quot;memory effect&amp;quot; may be of interest for design of new thermoelectric materials with&lt;br&gt;
controllable parameters&lt;/p&gt;</description>
