WebDOI: 10.1016/j.ceramint.2024.10.197 Corpus ID: 228963233; Phase transitions and elastic anisotropies of SiC polymorphs under high pressure @article{Ran2024PhaseTA, … The polymorphs of SiC include various amorphous phases observed in thin films and fibers, [3] as well as a large family of similar crystalline structures called polytypes. They are variations of the same chemical compound that are identical in two dimensions and differ in the third. Thus, they can be viewed as … See more Many compound materials exhibit polymorphism, that is they can exist in different structures called polymorphs. Silicon carbide (SiC) is unique in this regard as more than 250 polymorphs of silicon carbide had … See more A shorthand has been developed to catalogue the vast number of possible polytype crystal structures: Let us define three SiC bilayer structures (that is 3 atoms with two … See more All symbols in the SiC structures have a specific meaning: The number 3 in 3C-SiC refers to the three-bilayer periodicity of the stacking (ABC) and the letter C denotes the See more The different polytypes have widely ranging physical properties. 3C-SiC has the highest electron mobility and saturation velocity because of reduced phonon scattering resulting from the higher symmetry. The band gaps differ widely among the … See more • Silicon carbide fibers See more • A Brief History of Silicon Carbide Dr J F Kelly, University of London • Material Safety Data Sheet for Silicon Carbide See more
