Abstract: The Young''s modulus ( E) of a material is a key parameter for mechanical engineering design. Silicon, the most common single material used in microelectromechanical systems (MEMS), is an anisotropic crystalline material whose material properties depend on …
Silicon Carbide is a light, extremely hard, and corrosion resistant material which makes it a strong candidate for wear appliions in the harshest environments. Silicon Carbide also offers other desirable properties such as excellent thermal conductivity and high young modulus.
The two main properties of boron carbide are its very low density (2.5 g/cm3) and a hardness comparable to that of diamond. It is the third hardest material (Mohs > 9.5). In addition to its very high mechanical properties (Young''s Modulus, resistance to compression

Silicon carbide is a semiconductor that is now widely used in a variety of micro-electromechanical systems, light-emitting diodes and high-power electronics. Its technological appeal stems from the fact that it is amenable to mature, robust nanofabriion methodologies and possesses both a high Young’s modulus and excellent thermal conductivity. To many, silicon carbide is a material that
