Structure and electrophysical properties ofgasb-crsb eutectic composite

Abstract

XRD analysis and microstructure and DSC studies of GaSb-CrSb eutectic composite synthesized by the Bridgman method have been conducted. It has been shown that needle-shaped CrSb inclusions oriented to the solidification direction take part in the GaSb matrix. The initial and final temperature and enthalpy of melting for this composite have been determined. The anisotropy observed in the temperature dependences of Hall coefficient, electrical conductivity, and thermoelectric power of the composite has been attributed to the sort-circuiting effect of metallic inclusions.
