“…In accordance with results of EDX (energy dispersive X-ray spectroscopy) mapping, which was earlier reported earlier in Ref. [28], Bi, Te, Sm and Se are uniformly distributed within the particles, and, in accordance with results of SAED (selected area electron diffraction) experiment, the individual Bi 1.95 Sm 0.05-Te 2.7 Se 0.3 particles in the starting powder are single-crystalline particles with crystal Bi 2 Te 3 structure.…”

“…The Sm-doping effect on the particles size was already reported earlier in Ref. [28]. To analyse this effect, difference in the electronegativity of host Bi atoms and dopant Sm atoms was taken into account.…”

“…В настоящее время теллурид висмута (Bi 2 Te 3 ) и соединения на его основе, как электронного, так и дырочного типа проводимости, являются лучшими термоэлектрическими материалами для низкотемпературного применения. Одной из специфических характеристик теллурида висмута и соединений на его основе, заметно влияющей на их термоэлектрические свойства, является достаточно высокая анизотропия транспортных свойств, таких как электропроводность и теплопроводность [7][8][9][10][11][12][13]. Материалы на основе Bi 2 Te 3 обладают анизотропией кристаллической структуры, обусловленной главным образом сочетанием различных типов связей между атомами [7].…”
