Growth and characterization of single crystals in the series ZrSxSe2−x

Single crystals of transition metal dichalcogenide layered compounds with composition ZrSxSe2−x, where x varies within the range 0–2, were grown by the chemical vapour transport technique using iodine as a transporting agent. These binary solid solution crystals are found to be isomorphous over the whole range of composition. The growth conditions and lattice parameters were determined. X-ray diffraction was employed to determine accurate lattice parameters.
