2.3.4 Summary to: Conductors - General Applications

No electrical engineering without conductors!

Hundreds of specialized metal alloys exist just for "wires" because besides σ, other demands must be met, too: Money, Chemistry (try Na!), mechanical and thermal properties, compatibility with other materials, compatibility with production technologies, ...
Example for unexpected conductors being "best" compromise: Poly Si, Silicides, TiNW in integrated circuits.

Don't forget Special Applications:

  • Contacts (switches, plugs, ...); 
  • Resistors; 
  • Heating elements; ... 
  • Transparent conductors
