What is doping in semiconductors?
6 Doping in Semiconductors Doping is a crucial process in semiconductor technology that involves intentionally introducing specific impurity atoms into a semiconductor material. This deliberate introduction of impurities modifies the electrical and optical properties of the semiconductor, making it suitable for various electronic applications. Purpose of Doping The primary purposes of doping in semiconductors include: **Modifying Electrical Conductivity**: Doping can change the conductivity of a semiconductor material. Depending on the type of impurity added, it can either increase electron concentration (n-type doping) or create electron vacancies, also known as "holes" (p-type doping). These modifications enable the control of electrical conduction in semiconductor devices. **Tailoring Optical Properties**: Doping can also be used to tailor the optical properties of a semiconductor. For example, it can be employed to create materials that emit s
