Molybdenum disulfide is synthesized hydrothermally taking molybdenum trioxide and sodium sulfide as precursors in 0.4 mol/l HCl solution. Three approaches were pursued by varying two parametric factors: synthesis time and synthesis temperature. The products formed were characterized and analyzed using High Resolution Transmission Electron Microscopy (HRTEM) images. The mechanism involved in the formation of MoS2 along with the changes observed on changing the parametric factors is discussed. The Hall effect measurements give an insight regarding the important transport parameters like resistivity, mobility, type of conductivity and their charge carrier concentration. Present study attempts to explain the influence of synthesis time and temperature on the final morphology and transport parameters of the MoS2 formed. [ABSTRACT FROM AUTHOR]
