### Wide Bandgap Semiconductors Go Beyond Silicon | …

The popular WBG materials in use today are silicon carbide (SiC) and gallium nitride (GaN.) Whereas silicon possesses a bandgap of 1.1 electronvolts (eV), SiC and GaN have a bandgap of 3.3 eV and 3.4 eV, respectively. Insulators are materials with very large bandgaps, typically greater than 4 electronvolts (eV), and high resistivity.

### Silicon - Element information, properties and uses

Silicon makes up 27.7% of the Earth’s crust by mass and is the second most abundant element (oxygen is the first). It does not occur uncoined in nature but occurs chiefly as the oxide (silica) and as silies. The oxide includes sand, quartz, rock crystal, amethyst, agate, flint and opal.

### Why is stainless steel a poor conductor of electricity?

2020-7-12 · You are correct, stainless steel is a really poor conductor compared to most metals. This source lists it as $7.496 \times 10^{-7}\: \mathrm{\Omega \cdot m}$ which is more than 40 times worse than copper.. The reason is that conductivity in metals is high is that metals form a crystal lattice where the outer shell electrons are shared and easily move through the lattice.
