[0039] (1) Orient the crystal to (0001) Al 2 o 3 The substrate was ultrasonically cleaned in acetone solution for 10 min, then in absolute ethanol solution for 10 min, and finally in deionized water for 10 min, and dried with nitrogen.
[0040] (2) Al 2 o 3 Immerse the substrate in absolute ethanol and take it out after 1 min. When the ethanol is not completely volatilized, attach the through-hole AAO template on the substrate and let it dry; then, use a glass rod to dip a very small amount of ethanol and drop it onto the substrate without the template. Area of Al 2 o 3 On the substrate, let the ethanol diffuse spontaneously to the template area, and let it dry; repeat 2 times.
[0041] (3) Put the substrate transferred in step (2) into an oven and bake for a certain period of time. The oven temperature is 90°C, and the drying time is 2 minutes; take it out and let it cool down to room temperature.
[0042] (4) Put the sample processed in step (3) into the PLD chamber...
