Abstract :Pure and doped antimony selenide insert ignore into journalissuearticles values(Sb2Se3, Sb2Se2.8Te0.2, and Sb2Se2.6Te0.4); crystals have been grown from melt by the Bridgman Stockbarger method. X-ray powder diffraction analysis was carried out to determine the lattice parameters of the grown samples. The morphology of cleavage planes was observed using SEM. Energy dispersive analysis by X-rays insert ignore into journalissuearticles values(EDAX); was done to find out the chemical composition of the grown samples. Correlation of microhardness with other mechanical characteristics such as toughness, brittleness, and yield strength, has been investigated. The effects of Te doping on the mechanical behaviour and energy gap were also studied on the cleavage faces.
