Two-Dimensional and Screw Growth of MoS2 Films in the Process of Chemical Deposition from the Gas Phase

详细

The method of deposition from the gas phase is applied to the synthesis of thin films of molybdenum disulfide. It was established that varying the rate of temperature rise in the course of the synthesis affects the character of growth and the structure of the layers formed. With a decrease in the rate of temperature rise, a transition from standard two-dimensional to screw growth of MoS₂ films is observed. MoS₂ films produced as a result of screw growth have a high density of edge states, which makes them promising for use in catalysis.
