Gallium nitride (GaN) and silicon carbide (SiC) will displace silicon (Si) in power conversion due to higher performance and lower cost. GaN and SiC will service different segments of the market. GaN will take over consumer, telecom, and computer appliions, while SiC will be most prominent in industrial appliions that require higher voltages and current.

Silicium Carbide encourages expression and self-awareness of your creative energy. As a mineral for dreamers it is best placed by the bed for lucid dreams, and works as an amazing prism in crystal healing as it quickly disperses negative energy from around you.

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 .

Silicon Windows | Edmund Optics

TECHSPEC® Silicon (Si) Windows manufactured from optical grade silicon are popular for the 1.2 - 7μm spectral region due to their low cost and low density. Due to its low density (half that of germanium or zinc selenide), silicon is ideal for weight sensitive appliions, especially those in the 3 - 5μm region.
