What is Semiconductors?

Materials with electrical conductivity between conductors and insulators, which can be controlled by doping, temperature, or light. Silicon and germanium are the most important semiconductors, forming the basis of transistors, solar cells, and modern electronics.

Formula & Notation

n-type: donor dopant; p-type: acceptor dopant; Eg ≈ 1-3 eV

Other Names / Synonyms: Semiconductor material, doped semiconductor, electronic material

Properties & Characteristics

Semiconductors are materials with electrical conductivity intermediate between conductors and insulators, with a band gap typically between 1 and 3 eV. Their conductivity increases with temperature (unlike metals). Semiconductors can be intrinsic (pure) or extrinsic (doped with impurities). Silicon and germanium are the most widely used semiconductor materials.

Uses & Applications

Semiconductors are the foundation of modern electronics, including transistors, diodes, and integrated circuits. Solar cells convert light to electricity using semiconductor p-n junctions. LED technology relies on semiconductor band gap transitions to produce light.

Safety Information

Silicon and common semiconductor materials are generally low toxicity. However, some semiconductor compounds (arsenic, cadmium, lead compounds) used in advanced devices are highly toxic and require careful handling and disposal.

Always consult the SDS/MSDS before handling any chemical. This information is for educational purposes only.
