What are they?

A semiconductor has an electrical conductivity value falling between a conductor and an insulator. The electrical conductivity increases with increasing temperature, which is opposite to a metal. Semiconductor devices can display a range of useful properties such as passing current more easily in one direction than the other and sensitivity to light or heat.

What are they used in?

Semiconductors are found in:

  • cars
  • calculators
  • mobile phones
  • computers
  • TVs
  • railroads
  • so much more...
