Electrical conductivity value falling between that of a conductor, such as metallic copper, and an insulator, such as glass.
Some examples of semiconductors are silicon, germanium, gallium arsenide, and elements near the so-called "metalloid staircase" on the periodic table.
Chemical element with the symbol B and atomic number 5.
In its crystalline form it is a brittle, dark, lustrous metalloid; in its amorphous form it is a brown powder.

Density x EN plot elements.png values of the first 99 elements. Nonmetallic elements occupy the top left corner, having relatively low densities and moderate to high electronegativity values. Metalloids behave chemically like nonmetals but are sometimes treated as an intermediate class between the metals and the nonmetals.
Chemical element with the symbol Ge and atomic number 32.
It is a lustrous, hard-brittle, grayish-white metalloid in the carbon group, chemically similar to its group neighbors silicon and tin.
Chemical element with the symbol Si and atomic number 14.
It is a hard, brittle crystalline solid with a blue-grey metallic luster, and is a tetravalent metalloid and semiconductor.
Chemical element with the symbol Sb and atomic number 51.
A lustrous gray metalloid, it is found in nature mainly as the sulfide mineral stibnite (Sb2S3).
Chemical element with the symbol Te and atomic number 52.
It is a brittle, mildly toxic, rare, silver-white metalloid.
Chemical element with the symbol As and atomic number 33.
Arsenic is a metalloid.
Chemical element with the symbol Se and atomic number 34.
It is a nonmetal (more rarely considered a metalloid) with properties that are intermediate between the elements above and below in the periodic table, sulfur and tellurium, and also has similarities to arsenic.
Material that, when freshly prepared, polished, or fractured, shows a lustrous appearance, and conducts electricity and heat relatively well.
In chemistry, two elements that would otherwise qualify (in physics) as brittle metals—arsenic and antimony—are commonly instead recognised as metalloids due to their chemistry (predominantly non-metallic for arsenic, and balanced between metallicity and nonmetallicity for antimony).
