2.3.4 Summary to: Conductors - General Applications

  • Page ID
  • 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
