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.
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.
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.
The formula or notation for Semiconductors is: n-type: donor dopant; p-type: acceptor dopant; Eg ≈ 1-3 eV
