But although about 75% of the Earth is made from silica — or silicon dioxide (SiO 2), the main constituent of silicate minerals such as sand, quartzite or granite — elemental silicon itself is ...

The gate dielectric is a very thin insulation layer, traditionally made of silicon dioxide, that lies between the transistor's metal gate electrode and the channel through which the current flows.

Scientists from the University of Basel claim to have identified the causes of low near-interface mobility in the silicon carbides (SiCs) used in power electronics. With the Evidence for carbon ...
