Abstract
NixGe50–xTe50 with x = 2, 4, 6, 8, 10, 15 and 20 at% ternary nanocomposite prepared using multistage solid-state direct reaction. Nanocrystalline nature was studied by X-ray powder diffraction, results reviled that, the main phase is rhombohedral GeTe polymorph, and the second major phase is hexagonal Ni3GeTe2. The calculated average crystallite size of the whole constituents in prepared samples is within the range of 47.3-83.8 nm. Optical properties evaluated from diffuse reflection measurements and the calculated bandgap of all samples are nonmonotonically changes with Ni content from 1.45 to 1.62 eV with the direct allowed transition.
