Gallium Nitride, otherwise known by its chemical symbols as GaN, is a the ideal substance for radio energy amplification, which can work to enhance devices like radars and jammers. In past years, silicon was the substrate of choice for power electronics, but due to advancements in research, GaN has superseded silicon. The reason for this change is that GaN is considered a wide-bandgap material. This means that it has a high breakdown voltage and excellent efficiency when performing at high temperatures. If you need a UniversityWafer, Inc. product that will provide you with high quality and reliable results we suggest using our Gallium Nitride substrates.

GaN is a binary III/V direct bandgap semiconductor commonly used in bright light-emitting diodes since the 1990s. The compound is a very hard material that has a Wurtzite crystal structure. Its wide band gap of 3.4 eV affords it special properties for applications in:
For example, GaN is the substrate which makes violet (405 nm) laser diodes possible, without use of nonlinear optical frequency-doubling. Its sensitivity to ionizing radiation is low (like other group III nitrides), making it a suitable material for solar cell arrays for satellites. Military and space applications could also benefit as devices have shown stability in radiation environments.
Gallium Nitride transistors can operate at much hotter temperatures and work at much higher voltages than gallium arsenide (GaAs) transistors, they make ideal power amplifiers at microwave frequencies.

A researcher contacted us for the following: We are looking for the following layer stack: UID GAN (4,000-5,000 nm 4 - 5 micron) AlGaN Transition Layer AlN Nucleation Layer Si Substrate (111) can you let us know whether its available and with which wafer sizes ? Polished GaN surface is required.
Yes,It available and can supply,We do this type of HEMT GaN Epi stack on 4'',6'' and 8'' Silicon <111> wafer.
Epi surface roughness </=0.5nm,Pls confirm you still need the epitaxial finished surface to be polishing?
Thanks very much for your fast reply. You are completely right, the epitaxial finished surface would not need to be polished, my mistake.
Also, you spotted correctly that we only need the unintentionally doped GaN at the top of the layer stack and no further layers for high-electron-mobility-transistors.
May I ask you to clear these issues for me:

Gallium nitride has a lower electrical resistance and only loses a small amount of power. In addition, its low power consumption and low energy consumption allows the use of high-speed, low-power and high-frequency photonics in devices that operate on the basis of gan. GaN-based photonic technologies can be used every day for a wide range of biotechnological and scientific applications, including biomedical, medical, industrial, energy, optical, telecommunications, communications and energy storage applications.
GaN-based compound semiconductors have expanded their THz spectrum to ultraviolet and visible wavelengths with the continuous development of the material and devices, and have extended it to the THZ spectrum for the first time. According to the group, this progress opens up possibilities that can now be combined with macroscopic quantum effects of superconductors. The breakthrough will usher in a new era of optical compounds in silicon photonics and accelerate the development of sitoelectronic integration. OSRAM Opto - Semiconductor, which offers lighting, visualization and sensor technologies.
Fabricating electronic devices from Gallium Nitride instead of silicon, power consumption can be significantly reduced by emitting light into the ultraviolet range, which has shorter wavelengths. Researchers have succeeded in developing semiconductor compound semiconductor technology by using copper iodide semiconductors (CuI) made of copper, Cu and iodine (I), thereby ensuring a device technology that can emit blue light with high efficiency. By focusing on this point, they developed a new technology combining a combination of lead and copper-ionite compounds (lead-copper-iodine-I) to successfully emit blue light. This results in a much more efficient and energy-efficient electronic device with higher efficiency and higher performance.
Gallium nitride is likely to be a key material for improving the efficiency of emerging 5G technology. In particular, light-emitting semiconductors, which are replaced by gallianite, are expected to play an important role in the development of high-performance, cost-effective and high-performance electronics.
GaN semiconductors have shown in recent years that they are well suited for a wide range of applications, not only in electronics, but also in medical devices. Gallium nitride is currently widely used in real life radar designs, and it seems that its use is now also being used in tactical radios.
