The formative predictables of the microstructure metal-matrix composites, obtained using spark plasma sintering and consisting polycrystalline thermoelectric bismuth telluride Bi2Te3 (composite matrix) a ferromagnetic filler (Ni or Fe), were examined. It was determined that, in course sintering, inclusions form locally gradient nucleus–shell type (Ni@NiTe2 Fe@FeTe2) are formed randomly distribu...

The morphology studies of the interlayer surface (0001) were carried out by method scanning tunneling microscopy in n–Bi1.6Sb0.4Te2.94Se0.06, n- Bi1.8Sb0.2Te2.82Se0.09S0.09, p-Bi0.8Sb1.2Te2.91Se0.09 and p-Bi0.7Sb1.3Te2.91Se0.09 solid solutions. On (0001), impurity native defects found (vacancies tellurium, antisite defects, adatoms), formed compositions due to substitutions atoms Bi2Te3 sublatt...
