Embodiment 1
[0031] This embodiment provides a method for preparing molybdenum ditelluride nanowires on a silicon dioxide / silicon substrate, comprising the following steps:
[0032] Step 1: Cut the silica / silicon substrate into a 1cm*3cm sheet and blow it off with an air gun;
[0033] Step 2: Grind molybdenum powder and tellurium powder at a molar ratio of 1:4, mix well, place 2 mg of mixed powder on a silicon dioxide / silicon substrate, and add 0.1 mg of sodium chloride; A silicon dioxide / silicon substrate, SiO 2 Face down, upside down on the wafer;
[0034] Step 3: Place two silica / silicon substrates in a quartz tube with an inner diameter of 1.2 mm and one-end sealing, place the single-end-sealed quartz tube at the heating center of the tube atmosphere furnace, and single-end-seal the quartz tube The opening faces the side of the exhaust port, such as figure 1 as shown in a.
[0035] Step 4: Infuse 100 sccm of argon gas for 30 minutes to completely remove residual oxygen in the tube....
