Aluminum Nitride XRay Diffraction data are useful in analyzing the structural properties of AlN thin films. They help determine the crystalline quality of the materials. The diffraction peaks of aluminum nitride were measured on Mo/sapphire, Mo/SiO 2 and Si substrates. It was found that the diffraction peak of AlN on Mo/sapphire was much stronger than that of AlN thin film on the SiO 2 sandstone substrate.
XRD measurements of AlN were performed on pure Al at 200-300W power. The pressure of 1mTorr was selected because it was the best compromise between relative (002) XRD peak intensity and film stress. The 2:1 Ar/N 2 flow ratio was applied to all experiments. The lower pressure was used for sample M15 because of the higher crystalline structure of the material.
XRD measurements were performed on single locations on a single sample, which is known as the rocking curve. The sample was fixed at the 2nd peak position and was subsequently shook across the o axis to measure the film's stress. By combining the diffraction data with SEM analysis, the biaxial stress of the film was calculated from XRD measurements.
XRD measurements of AlN were obtained by using a reactive sputtering technique, which was done on a sapphire substrate. The AlN layer was grown with a preferred orientation in the (110) plane. In contrast, Mo layers without AlN depositions were used to measure the diffraction data of AlN. The analysis showed that the two materials were in close proximity to each other and had similar diffraction patterns.
The results from the ALN XRD data were interpreted according to the rocking curve. For instance, the XRD diffraction peak was observed in the region of the sample with the 2nd at the (002) peak position. This result showed that the material had high crystalline structure with low atomic number. The results were analyzed using the diffraction method. Aside from diffraction, the diffraction pattern showed the structural characteristics of AlN.
The ALN XRD data were obtained from a series of measurements. In this study, the Mo electrode was grown on an AlN substrate with the preferred orientation in the (110) plane. The AlN film was grown on AlMo in a different way with the sputtering parameters. The result showed that the Mo films had improved surface roughness compared to pure aluminum. The aluminum films were found to have a better surface roughness.

When comparing sapphire with alumina, the latter is more durable. Sapphire is one of the hardest natural materials known to mankind and has a high melting point of more than 2000degC. It is also chemically inert, meaning it is resistant to many types of chemicals. Unlike alumina, sapphire has a wide range of colors and transmits ultraviolet, visible, infrared, microwaves, and x-rays.
The difference between alumina and sapphire lies in the process of crystallization. Alumina is a single crystal of alumina and has a uniform orientation. When compared to sapphire, the latter is more resistant to heat than alumina. In addition to the differences between alumina, there are many similarities between the two materials. Artificial sapphire is a synthetic sapphire that is grown under careful control in a lab.
The structure of sapphire is hexagonal, and it belongs to the R3c space group. Its crystalline structure is a single crystalline form of corundum, which is also known as alumina or alpha-alumina. The crystalline structure is formed by intercalating aluminum planes with oxygen planes. In sapphire, two-thirds of the sites are vacant, and its aluminum/oxygen ratio is 2:1. The oxygen atoms have six Al neighbours, while the aluminum atoms are paired with six oxygen atoms. Ultimately, a sapphire can be cut along its rhombohedral planes, which make it cleavable.

In extreme cases where no other reflections are present in the XRD data, the preferred orientation of the TC reaches the maximum value of n. This position corresponds to the pressure load of the powder data at 36.04 degrees on the film. The observed RD peaks can be assigned to either Wurtzite or AlN, but not to both. [Sources: 3, 5]
The discrepancy in the actual size shows, however, that the grains on the film surface may not be entirely made of AlN, which contains an oxide shell that cannot be examined in the X-ray image. The average grain size obtained from the X-ray diffraction data for Wurtzite and Aln is also consistent with the actual grain size of the powder data and the grain-to-film ratio. [Sources: 0]
