How is a pure semiconductor changed into an N-type material?
An N-type semiconductor is created when pure semiconductors, like Si and Ge, are doped with pentavalent elements. When a pentavalent atom replaces a Si atom, four of its electrons bond with four neighboring Si atoms, leaving one free electron.
What is the difference between P and N type materials?
N-type semiconductors have an excess of electrons, while P-type semiconductors have an excess of "holes" where an electron could exist.
What are the uses of diodes?
The most basic function of a diode is changing AC current to DC current by removing some part of the signal. This makes them rectifiers. They are also used in electrical switches and surge protectors because they can prevent voltage... Continue reading "Key Concepts in Electronics, Energy, and Basic Science" »
