Silicon - McGill School Of Computer Science

Silicon ( IPA: /ˈsɪlikən/, Latin: silicium) is the chemical element in the periodic table that has the syol Si and atomic nuer 14. A tetravalent metalloid, silicon is less reactive than its chemical analog carbon. It is the second most abundant element in the Earth ''s crust, making up 25.7% of it by mass. It does not occur free in nature.

The Young''s Modulus of Silicon

Anisotropic Elasticity Hooke''s law describes the linear, isotropic relationship between stress (σ) and strain (ε) using compliance (S) and stiffness (C):σ=Cε , or ε=Sσ . The mechanical stiffness of materials under uniaxial loading is called the Young''s modulus, and is typically represented by the syol E in engineering texts, so Hooke''s law is often written as σ=Eε .
