Optical properties of alpha silicon carbide. - NASA/ADS
Laboratory extinction spectra of grains of α silicon carbide are available which compare well with the astronomical observations. Unfortunately, these measurements are not sufficient to fully interpret the 11.5 μm feature profiles since radiative transer models require the knowledge of the complex refractive index of the circumstellar material over the whole electromagnetic spectrum.

Optical properties of boron carbide (B5C) thin films …
The index of refraction n, the extinction coefficient k, and the absorption coefficient are reported in the photon energy spectrum between 1.24 and 4 eV. Ellipsometry analysis of B 5 C films on silicon indies a graded material, while the optical constants of B 5 C on glass are homogeneous.
Thermal oxidation of 3C silicon carbide single-crystal …
Thermal oxidation of thick single-crystal 3C SiC layers on silicon substrates was studied. The oxidations were conducted in a wet O2 atmosphere at temperatures from 1000 to 1250 °C for times from 0.1 to 50 h. Ellipsometry was used to determine the thickness and index of refraction of the oxide films. Auger analysis showed them to be homogeneous with near stoichiometric composition
Scalable Quantum Photonics with Single Color Centers in Silicon Carbide
ABSTRACT: Silicon carbide is a promising platform for single photon sources, quantum bits (qubits), and nanoscale sensors based on individual color centers. Toward this goal, we develop a scalable array of nanopillars incorporating single silicon vacancy
Navarro SiC - Silicon Carbide
Silicon carbide develops in the furnace as a solid cylindrical ingot around the graphite core, with concentric layers that decrease their SiC content with the distance from the core. It can be black or green depending on the composition of the raw materials used.
List of semiconductor materials - Wikipedia
Semiconductor materials are nominally small band gap insulators.The defining property of a semiconductor material is that it can be doped with impurities that alter its electronic properties in a controllable way. Because of their appliion in the computer and photovoltaic industry—in devices such as transistors, lasers, and solar cells—the search for new semiconductor materials and the

Talk:Diamond simulant - Wikipedia
That is why I have coined the "Index(es) of Refraction" column and the single/double refraction column. It is also why I have used line breaks and abbreviations to keep each column narrow. Thank you for mentioning this issue -- I need to remeer that my browser will render the table at a different width than some other browsers, especially if the font sizes are different.
