Atomistic modeling of amorphous silicon carbide: an approximate first-principles study in constrained solution space
Silicon Carbide SiC 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.
In this paper we study the Young''s modulus of PECVD obtained silicon rich (x > 0.5) a-SixC1-x:H thin films through the study of the resonance frequency of free standing cantilevers. These structures are fabried based on front side bulk micromachining of Si substrate and actuated thermally. In this approach, an alternating electric current …

Young’s modulus may be thought of as a substance’s resistance to elastic deformity; the stiffer the material, the higher its elastic modulus. For the majority of metals, this modulus ranges from 45 GPa (gigapascals) in the case of magnesium to 407 GPa for tungsten.
Elastic Modulus The Elastic or Young''s modulus ( E ) describes tensile elasticity, or the tendency of an object to deform along an axis when opposing forces are applied along that axis; it is defined as the ratio of tensile stress to tensile strain. Shear Modulus
