I'm interested in purchasing m-plane sapphire substrates for MOCVD epitaxial growth of gallium oxide. Could you let me know what is the cost per wafer (looking to purchase 10-20 wafers). Also do you provide have miscut m-plane sapphire substrates with 2, 4 degree miscuts? Also, could you let me know what is the RMS roughness of your epi ready m-plane sapphire substrates.

What is M-Plane Sapphire?
I have increased the number of layers in the double Aln buffer layer used by the M-plane SAPPHIRE (reported here). It has grown to over 1,000 layers, up from fewer than 500 layers last year, and is growing faster than the average of 2,500 layers with double aln buffer layers. I have increased the amount of layers in both the single and multiple layers, from about 200 layers this year and up to about 400 layers now. It also grows faster than a single anecdotal layer, which uses a double aln buffer layer. [Sources: 6, 7]
High-resolution X-ray diffraction measurements have shown that the XRD pattern of the M-plane SAPIRE is azimuthal in the only Aln buffer layer - dependent. The FFT pattern is shown below, derived from the above RD results and the high-resolution X-rays. [Sources: 3, 7]
The measurement data presented are based on testing on certain sapphires, but other sapphires have different strengths depending on the type of cultivation. The plane axis of the sapphire can be determined from the actual sapphire of a single crystal and analyzed with high-resolution X-ray diffraction and X-ray measurements. Synthetic sapphire is grown in popular crystal directions, including levels A, C, R and M (see illustration below). [Sources: 0, 2]
In the case of plansapphires, the M axis is always much stronger than the C axis, but the absolute strength values can vary depending on the production path. An example measurement could indicate that the A-plane of a sapphire, when tested in the A-axis, has a strength of 450 MPa, and when tested in a plane of the m-axis, its elements will have a strength of 1200 MP a. The M-axes can be tested for strength in any direction. [Sources: 2]
Under MOCVD growth conditions, the surface of the Sapphire Square is 11 x 22 planes, and the angle between the 1102 and 1100 planes of Safiren is 32 x 28 degrees. The Ga-N source tends to form a pattern similar to the 1.0, but this surface is aligned at a plane of 2.5 degrees to the M axis, rather than the C axis. [Sources: 1, 7]
The optical element 320 was developed by enlarging the crystallographic structure of the sapphire (310) to the desired plane in order to recognize the plane axis of the sapphire crystal. The use of the defined crystal plane as optical elements was processed into a sapphire crystal and its 310 planes were configured to run parallel to the M axis, giving it an improved strength. [Sources: 2]
M plane in sapphire, the surface of the sample is parallel to the axis, and the M plane is defined as the plane axis on the right side of the plane. Once we know that the crystal is in an M plane, we can use this axis to determine the orientation of each unit cell in a crystal. [Sources: 5]
To solve this problem, we built two superlattices of two layers of sapphire, one in the M plane and the other in an aln. As you can see, the interface runs clearly parallel to the surface of the formed alns, which are aligned in the direction of the m plane. M levels are oriented to the as, while the forming alNs are oriented to the 11 level of Sappshire. [Sources: 1, 3]
We are interested in studying the properties of the sapphire in the M plane and the m plane of the Aln, as well as the relationship between the two. We grew and deposited two layers of a thick PDMS top layer with a thin layer of polydimethylsiloxane (PdMS) on the surface of a layer and grew it in Sappshire 0001 by pulsed sputtering. The membrane was tilted upside down into a steel bracket, manually peeled from the Sapshire substrate and then deposited on a high-pressure, low-pressure polymer substrate. [Sources: 1, 6]
The shape and microstructure of the sapphire are difficult to control accurately, but we can observe that the etching effect increases as the thickness of the aln. increases with the nitridation time, as if it were a symbol of saffir. 1) indicates the presence of an etching effect in the M plane, which indicates an oriented aln formation in a nitrided sapphire. The reflection of the algae can be seen as 90 degrees away from the spheres, suggesting that they are included in the m plane and not vice versa. [Sources: 3, 4]
By determining the different layers of the sapphire crystal and by designing and controlling the desired anisotropy of the sawdust, it is possible to maximise the use of mobile devices. We have already collected data at the level of a sapphire and are now investigating the m-plane sapthshire to see how the change in orientation of this substrate affects the formation of aln in a sample obtained from it. First, we compare the interface that forms between the M plane and the surface of an organic substrate (1, 2). [Sources: 1, 2, 5]
Table 1 shows the GaN domains growing on the patterned m-plane sapphire substrate and the changes in its orientation. We investigate the effects of the change in the orientation of Aln in a sample of a m-plane sapphire on its patterned substrate. [Sources: 1]
