Metalloid - Wikipedia

Silicon dissolves in hot aqueous alkalis with the evolution of hydrogen, as do metals such as beryllium, aluminium, zinc, gallium or indium. It melts at 1414 °C. Silicon is a semiconductor with an electrical conductivity of 10 −4 S•cm −1 and a band gap of about 1.11 eV.

Doping (semiconductor) - Wikipedia

For example, the E B for boron in silicon bulk is 0.045 eV, compared with silicon''s band gap of about 1.12 eV. Because E B is so small, room temperature is hot enough to thermally ionize practically all of the dopant atoms and create free charge carriers in the conduction or valence bands.
