Embodiment 1
[0049] 1. A silicon wafer (300nm thick oxide layer) with a single layer of molybdenum disulfide will be grown by chemical vapor deposition, as follows:
[0050] a1) Put the substrate into deionized water, acetone and isopropanol in sequence for ultrasonic cleaning, then dry it with nitrogen, and place it on the double-ended substrate with transition metal oxide (preferably molybdenum trioxide) Open the quartz boat and put it into the reaction chamber of the high temperature tube furnace;
[0051] b1) placing a quartz boat equipped with chalcogen simple substance (preferably sulfur powder) on another heating belt relative to the upper end of the base gas flow;
[0052] c1) After purging with argon gas in the tube furnace, 5 sccm of argon gas is introduced, and after the gas flow is stable, the chalcogen element and the transition metal oxide (silicon wafer) are heated separately, and the monolayer can be obtained by growing on the substrate. layer transition metal chalcogenide; ...
