1-3.Mohs Hardness
Rough measure of the resistance of a smooth surface to scratching or abrasion, expressed in terms of a scale devised(1812)by the German mineralogist Friedrich Mohs. The Mohs hardness of a mineral is determined by observing whether its surface is scratched by a substance [...]

5-2-2-1 SiC Crystallography: Important Polytypes and Definitions
Silicon carbide occurs in many different crystal structures, called polytypes. A more comprehensive
introduction to SiC crystallography and polytypism can be found in Reference 9. Despite the fact that
all SiC polytypes chemically consist of 50% carbon atoms covalently bonded [...]

2-29.Resistivity
The resistance to current flow and movement of electron and hole carries in the silicon carbide. Resistivity is related to the ratio of voltage across the silicon to the current flowing through the silicon carbide per unit volume of silicon carbide. The units for [...]

3-10. Carrots
Similar to comet tails in appearance except they are more angular and lack a discrete head. If present, these features are aligned parallel to the major at. Usually,any carrots present tend to be of the same length. Count once per occurrence. Two [...]
