Semiconductors and transistors

Semiconductors, which can be found in diodes and other devices, are materials that have an electrical conductivity between conductors.
A silicon crystal can function as an insulator, which allows the flow of electricity only in little amounts. Silicon is an element of periodic table from which transistors are made. Moreover, silicon can be turned into a conductor by means of doping, where either N-type or P-type impurity is mixed. …
