Analyze Silicon Carbide (SiC) with the inVia Raman Microscope

Analyze Silicon Carbide (SiC) with the inVia Raman Microscope

10 Nov 2015

Silicon carbide has significant advantages over silicon, such as a wider band gap, higher thermal conductivity, and higher breakdown field. It is also chemically and thermally inert. These properties make it attractive for use in transistors (JFETS, MOSFETs, etc.) in applications such as high temperature electronics, and in fast high voltage devices for more efficient power transmission and high temperature operation. The properties of silicon carbide are highly dependent on its crystal structure (it can exist in many polytypes), on the quality of the crystal, and on the number and types of defects present. This application note demonstrates the analysis of SiC using Raman microscopy.

Raman SpectroscopyRaman spectroscopy is used to discern the vibrational and rotational states of molecules and hence the chemical composition of a sample by measuring the inelastic scattering of monochromatic light. Explore a range of Raman spectrometers, including handheld/portable Raman spectrometers for QC/QA labs and in situ spectrometers for processes. Conduct Raman imaging for microanalysis of mixed samples using a Raman microscope. Raman spectrographs are also available. Find the best Raman spectroscopy products in our peer-reviewed product directory: compare products, check customer reviews and receive pricing direct from manufacturers.Particle CharacterizationParticle characterization instruments are used to determine particle size distribution, shape, surface area, zeta potential, density and porosity of particles and materials. Multiple tecchniques are available for determining particle size, shape and count including dynamic light scattering (DLS), laser diffraction, electrozone (Coulter technique), imaging particle analysis and single particle optical sensing. Determine the density of your material with a gas pycnometer or examine its surface area and porosity with gas adsorption analyzers and mercury porosimeters.

Common methods include ultrasonic, magnetic-particle, liquid penetrant, radiographic, remote visual inspection (RVI), and eddy-current testing. NDT is regularly used in forensic engineering, civil engineering, mechanical engineering, electrical engineering, systems engineering, aeronautical engineering, and medicine.SiliconCrystallization
