Semiconductor: A material with conductivity between conductors and insulators that can be controlled.
Explanation
Semiconductors like silicon and germanium have intermediate conductivity that can be controlled by adding impurities or applying voltage. Semiconductors form the basis of modern electronics including transistors and diodes. In semiconductors, conduction occurs through the movement of electrons and electron holes. Doping semiconductors with impurities creates P-type and N-type semiconductors used in electronic devices. Temperature affects semiconductor conductivity.
Example
Silicon is a semiconductor used in computer chips where its conductivity can be precisely controlled to create electronic switches.
