Infrared spectroscopy of silicon carbide layers

It has been found that, in the infrared spectra, there is a band at 798 cm-1, which corresponds to a transverse optical (TO) phonon in the lattice of silicon carbide. The parameters of disordered silicon carbide on the surface of pores between the epitaxial layer of silicon carbide and the silicon substrate have been determined.

Reflection Measurements in IR Spectroscopy - PerkinElmer

Spectra of soft drink bottles on silicon carbide abrasive. Diffuse reflection spectra in the mid-IR are generally used for qualitative identifiion of powders. Because sample preparation need involve no more than mixing with KBr the method is simpler and more rapid than making a KBr pellet. In principle diffuse reflection spectra can be used

Silicon oxycarbide glasses: Part II. Structure and

Carbon is bonded to either silicon or carbon; there are no carbon-oxygen bonds in the glass. Infrared spectra are consistent with these conclusions and show silicon-oxygen and silicon-carbon vibrations, but none from carbon-oxygen bonds. 29 Si-NMR shows evidence for four different bonding groups around silicon. The silicon oxycarbide structure

Mar 10, 2008· Abstract: Silicon Carbide (SiC) optical constants are fundamental inputs for radiative transfer models of astrophysical dust environments. However, previously published values contain errors and do not adequately represent the bulk physical properties of the cubic (beta) SiC polytype usually found around carbon stars.

The Working Principle and Key Appliions of Infrared Sensors

The infrared spectrum can be split into near IR, mid IR and far IR. The wavelength region from 0.75 to 3µm is known as the near infrared region. Sources of infrared radiation include blackbody radiators, tungsten lamps and silicon carbide. Infrared sensors typically use infrared lasers and LEDs with specific infrared wavelengths as sources.
