Explanation

Semiconductors (silicon, germanium) have conductivity between conductors and insulators. Their conductivity increases with temperature – opposite of metals.

Doping adds impurities to create n-type (extra electrons from Group V elements) or p-type (missing electrons/holes from Group III elements) semiconductors.

P-n junctions form diodes – conduct one way only. Transistors (npn or pnp) amplify signals and switch. Semiconductors enable all modern electronics.
