Semiconductors are a category of elements known as metalloids.

Here's why:

* Metalloids are elements that have properties of both metals and nonmetals.

* Semiconductors are materials that have electrical conductivity between that of a conductor (like copper) and an insulator (like rubber). Their conductivity can be precisely controlled by adding impurities (doping) or by applying an electric field.

The most common semiconductors are:

* Silicon (Si)

* Germanium (Ge)

Other elements considered metalloids and also used in semiconductor applications include:

* Boron (B)

* Arsenic (As)

* Antimony (Sb)

* Tellurium (Te)
