Abstract: The aim of the work is to study the electrical conductivity of composite single crystals $(InSb)_(98.2) -- (NiSb)(1.8)$. Single crystals of the composite eutectic system $(InSb)_(98.2) -- (NiSb)(1.8)$ were obtained using the modified Bridgman method. The composition and distribution homogeneity of elements were determined by the energy-dispersive X-ray spectroscopy method using a JSM-6610LV (Jeol) scanning electron microscope. The intervals of hopping conductivity with a variable jump length of the Shklovsky-Efros type and by the nearest neighbors were determined for samples with different orientations of needle-shaped inclusions of $NiSb$ single crystals.

Keywords: inSb-NiSb, single crystal, electrical properties, hopping conductivity.
