A rule-breaking, colorful silicone that could conduct electricity. Previously only thought to be insulating, a shift in the ...

Semiconductors are at the heart of most electronics. We explain what semiconductors are, how they work, and just how tiny those transistors can get.

A semiconductor is a material product with some of the properties of both insulators and conductors (hence semi, meaning half or partial, conductor). Semiconductors are usually comprised of ...

Semiconductors. Semiconductors are materials with electrical conductivity between that of conductors and insulators. Materials like silicon, germanium, and gallium arsenide exhibit selective ...

Revise conductors, semiconductors, insulators and p-n junctions for your Higher physics exam with Bitesize Scotland interactive practice quizzes covering feedback and common errors.

An insulator will have a large band gap, making it impossible for electrons to circulate by being excited into the conduction band. In contrast, conductors have a band gap of almost zero and so will ...
