Example Embodiment
[0050] Example 1
[0051] 1. Take the size of 8cm×8cm foam nickel and place it in the tube furnace;
[0052] 2. Turn on the vacuum pump to pump the air pressure of the tube furnace to the ultimate vacuum state 3×10 -6 Torr;
[0053] 3. Maintain a vacuum state 3×10 -6 After Torr for 15 minutes (the effect of vacuum for 15 minutes is to remove impurities and air inside the quartz tube to ensure that the reaction chamber is clean), increase the air pressure of the quartz tube 3 to 3×10 -3 Torr;
[0054] 4. Set the hydrogen flow meter to 100sccm and inject hydrogen into the vacuum chamber;
[0055] 5. After the temperature of the tube furnace is raised to 300°C, annealing is performed at a constant temperature for 20 minutes;
[0056] 6. After the temperature of the tube furnace is raised to 1000°C, inject methane into the vacuum chamber, set the gas flow meter to 200sccm, and stay for 30 minutes for growth;
[0057] 7. Turn off the methane gas flowmeter and quickly drop the tube furnace temp...
