What You Need to Know About Semiconductors
Semiconductors are a class of materials with special electrical properties that lie between those of conductors and insulators. They enable precise control of electric current and are therefore indispensable for modern electronic applications. The most important semiconductor materials are silicon and germanium, which belong to the fourth main group of the periodic table. The electrical conductivity of semiconductors can be influenced by doping, i.e., the targeted introduction of foreign atoms. This creates n-doped (electron surplus) or p-doped (electron deficiency) semiconductors. [...]
