p–n junction
A p–n junction diode.The circuit symbol is also shown. A p–n junction is a combination of two types of semiconductor materials, p-type and n-type, in a single crystal.The "n" (negative) side contains freely-moving electrons, while the "p" (positive) side contains freely-moving electron holes..
Understanding the difference between n
In silicon doping, there are two types of impurities: n-type and p-type. In n-type doping, arsenic or phosphorus is added in small quantities to the silicon. Both of these elements have five electrons in their outer orbitals and so they are not out of place when they get into the silicon crystalline structure.
