Laser fabriion of silicon carbide detector for gas …
The detector absorbs the photons and the absorbed photon energy modifies the electron density in the semiconductor by the photoexcitation, leading to changes in the refraction index. Ga is known to have an energy level of 0.30 eV in n-type 4H-SiC substrates, which corresponds to the wavelength 4.21 μm.

This map shows which countries export or import more of Silicon carbide.Each country is colored based on the difference in exports and imports of Silicon carbide during 2018.In 2018, the countries that had a largest trade value in exports than in imports of Silicon carbide were China ($352M), Norway ($87.9M), Brazil ($51.1M), Netherlands ($41.4M), and Russia ($32.9M).
An uncooled mid-wave infrared detector based on optical …
This dissertation focuses on an uncooled Mid-Wave Infra-Red (MWIR) detector was developed by doping an n-type 4H-SiC with Ga using the laser doping technique. 4H-SiC is one of the polytypes of crystalline silicon carbide, a wide bandgap semiconductor. The dopant creates an energy level of 0.30 eV, which was confirmed by optical spectroscopy of the doped sample. This energy level corresponds to
AR-Coated Windows | II-VI Incorporated
Because the infrared transmitting material has a high index of refraction, an anti-reflection coating is typically applied to windows to minimize losses due to reflections. For guidelines about calculating the proper thickness for a window to withstand a given pressure, see our Pressure Loading tutorial.
Abrasive for these machines includes alumina and silicon carbide, which use a vitrified or resinoid bonding agent. It is in the vitrified whetstone where our frit is used as bonding agent. We also use our advanced technology to provide products meeting the needs of our customers in such a niche field.

Silicon Carbide Conductive Wafers Product Description: Due to Silicon Carbide (SiC) physical and electronic properties, SiC based devices are well suitable for short wavelength optoelectronic, high temperature, radiation resistant, and high-power/high-frequency electronic devices, compared with Si and GaAs based devices.
The Correct Material for Infrared (IR) Appliions
Index of Refraction – IR materials vary in terms of index of refraction far more than visible materials do, allowing for more variation in system design. Unlike visible materials (such as N-BK7) that work well throughout the entire visible spectrum, IR materials are often limited to a small band within the IR spectrum, especially when anti-reflection coatings are applied.
