The supernatant containing 2D nano-flakes of Molybdenum di-sulphide (MoS 2 ) are synthesized and collected using wet chemical synthesis process. The dispersed MoS 2 nano-flakes solution is having strong absorbance values at 627 nm and 690 nm conforming to an energy band gap BG of 1.79 eV and 1.98 eV. Thereafter, MoS 2 thin films with and without magnetic doping (cobalt) are deposited on n type silicon by spin coating technique. These samples are placed in the quartz boat then and annealed in a thermal furnace at 260 o C for 40 min in Nitrogen gas environment. The AFM imaging of these samples revealed average lateral dimensions of nano-flakes to be from 100 to 200 nm. The magnetization curves with respect to the applied field for both samples are studied using Vibrating Sample Magnetometer (VSM). The VSM measurements, conducted at room temperature, verified the presence of the magnetic property that was introduced, as well as the hysteresis loop, in the thin films of Cobalt-doped MoS 2 .
Keywords: MoS 2 , Wet chemical synthesis, Thin film deposition, Spin coating, Optical properties, Magnetic properties.
