Electrical transport properties of semiconducting chromium molybdenum diselenide single crystals

Mixed chromium–molybdenum diselenides (CrxMo1−xSe2 (x=0.25, 0.50, 0.75)) have been grown in single crystalline forms by the chemical vapor transport technique. Electrical transport properties like electrical resistivity (perpendicular and parallel to the c-axis), thermoelectric power measurements at high temperature and Hall effect measurements at room temperature were performed on these single crystals. Preliminary study of electrical measurements suggest a semiconducting behavior of CrxMo1−xSe2 (x=0.25, 0.50, 0.75) single crystals. Data of Hall coefficient and thermoelectric power have good agreement with each other and confirms the p-type nature of these crystals. Our findings should motivate an in-depth investigation of the underlying mechanisms.
