AlN crystals are one of the representative III-V group semiconductor materials.
Experimental Method This experiment adopts the simulation method to act out the temperature field of AlN growth chamber, the original structure as shown in Figure 1, the chamber is made of high purity tungsten materials, and heating process can avoid secondary pollution.
The temperature distribution of seed is low, the surface temperature of materials is high, the central temperature is high, and the edge temperature is low.
