no conductor (n)

Nichtleiter (m)

insulator (n)

Unlike insulators and semi-conductors, conductors have a large number of freely moving charges.

Semi-conductors are substances that can be considered as insulators at a temperature of 0 degrees Kelvin but become more conductive as the temperature increases.
