Molecular Beam Epitaxy is a process that builds layers of molecules on a substrate, or matrix. The apparatus used in MBE is called a growth chamber. The growth chamber contains a number of nozzles that fire molecules onto the substrate in the center. In addition to the growth chamber, an MBE machine typically has many chambers which can be used for different purposes such as deposition, etching and cleaning.

Molecular beam epitaxy (MBE) is a method of depositing thin films of material onto a substrate. The substrates used for MBE depend on the specific materials being deposited, but some common choices include:
Single crystal substrates: These are often used for growing crystalline films of the same material. Examples include silicon for silicon films or sapphire for aluminum gallium nitride films.
Epitaxial substrates: These are often used for growing crystalline films of a different material. Examples include gallium arsenide for indium gallium arsenide films or yttrium-stabilized zirconia for high-temperature superconducting films.
Amorphous substrates: These are used for growing films that do not require a crystalline structure, such as amorphous silicon films.
Hybrid substrates: These are used for growing complex heterostructures made of different materials. Examples include silicon-on-insulator substrates or GaAs/AlGaAs superlattice substrates.
Overall, the choice of substrate for MBE depends on the specific materials being deposited and the desired properties of the resulting films.
A PhD student requested help with the following question:
I work in a group that does a lot of MBE growth. We're interested in your sapphire wafers, specifically the 50.8mm diameter, 430 micron thick, SSP wafers. Can you tell me the difference between the "C to M-plane by 0.2ą0.1 deg off" and "M-plane" variants?
Also, do you have any technical information about the sapphire wafers? e.g.
UniversityWafer, Answered:
The "C to M-plane by 0.2ą0.1 deg off" and "M-plane" refer to different orientations or planes of sapphire crystal used in various applications, primarily in semiconductor and optics industries. Let's break down the terms to understand the differences:
M-plane Sapphire: The M-plane refers to a specific orientation of the sapphire crystal lattice. Sapphire is a form of aluminum oxide (Al2O3) crystal, and its crystal structure can be oriented in various planes, each with unique properties. The M-plane is typically perpendicular to the C-plane and has its own set of properties such as surface energy, chemical reactivity, and atomic arrangement, making it suitable for specific applications.
C to M-plane by 0.2ą0.1 deg off: This description refers to a sapphire crystal orientation that is slightly off from the M-plane. The "0.2ą0.1 deg off" part indicates the crystal is oriented at an angle that is 0.2 to 0.1 degrees away from the perfect M-plane alignment. This small angular difference can significantly affect the surface properties of the crystal. Such off-angle sapphire is often used in specialized applications where the exact orientation of the crystal lattice affects the material's performance, such as in epitaxial growth of semiconductor materials.
The key difference between these two lies in the precision of the crystal orientation. The M-plane sapphire has a specific, standard orientation, while the "C to M-plane by 0.2ą0.1 deg off" variant is intentionally misaligned by a small angle. This slight misalignment can influence factors like the way films grow on the sapphire substrate in semiconductor manufacturing. Depending on the application, one may choose a standard M-plane sapphire for its specific properties or an off-angle variant to take advantage of the altered surface characteristics resulting from the slight misorientation.

The question "What is molecular beam epitaxy?" is a good place to start. Molecular Beam Epitaxy is a process that builds layers of molecules on a substrate, or matrix. The apparatus used in MBE is called a growth chamber. The growth chamber contains a number of nozzles that fire molecules onto the substrate in the center. In addition to the growth chamber, an MBE machine typically has many chambers.
Molecular Beam Epitaxy is a process used to grow nanoparticles of material by bombarding them with a high-pressure gas. It is performed in ultra-high-vacuum chambers that operate at temperatures around 932degF and 500degC. The chambers are designed to be completely dust-free, since even the smallest amount of contamination can ruin a crystal.
Molecular Beam Epitaxy was invented by John R. Arthur Jr. and is a form of chemical vapor deposition. In this process, silicon is evaporated one layer at a time. The process does not involve chemical reactions, and is done at ultra-high vacuum pressures. The growth rate is typically between 0.01 and 0.3 mm/s. This method is ideal for creating nanoparticle-based devices.
Molecular Beam Epitaxy is a technique that uses a laser to generate layers of atoms. It is a method that studies the growth of crystals and superlattices. During the process, a microscope is used to monitor growth rates and film thickness. A variety of other parameters can also be measured, including atomic coverage, adhesion coefficient, evaporation coefficient, surface diffusion distance, and more.
MBE uses a laser to create molecules. MBE can use gas or a liquid source to create MBE beams of AsH 3 or PH 3 or even metal-organic compounds carried by hydrogen flows. This type of MBE is also known as metalorganic MBE. It has numerous advantages. The research results of the Molecular Beam Epitaxy system market are useful for manufacturers, investors, and researchers.
Molecular Beam Epitaxy is a technique that studies the growth of crystals and superlattices using ultra-high-pressure chambers. It is an effective method for creating semiconductors, as it can minimize autodoping and autodiffusion. Because the process is based on evaporation, it can also produce a complex doping profile. During the process, the silicon and dopants are deposited one by one.
