What are Semiconductors?. Semiconductor material is a substance which has electrical conductivity between conductors and a non-conductor or insulator. Semiconductors are the core fundamental materials which are used in solid-state electronic devices such as transistors, diodes etc. The material’s atomic structure decides whether the material will turn out to be a metal, semiconductor or insulator. .
