Why is silicon preferred over germanium in preparing diode?
That's interesting. How does doping affect the performance of diodes?
Doping is the process of intentionally adding impurities to a semiconductor material in order to change its electrical properties. In diodes, doping can be used to create regions with excess electrons (n-type) or regions with excess holes (p-type). This helps to create a depletion region at the junction between the two regions, which allows the diode to conduct current in one direction only.
