NPNP full form

NPNP full form

Negative-Positive-Negative-Positive (semiconductors)

What is the meaning of NPNP and full form ?

The idea of using semiconductor materials in modern day electronics stems from the fact that the way the positive and negative electrons are arranged in the material are unique as compared to other materials in the real world.The point where they meet are known as a pn junction and the subsequent layers can be in the format of NPNP.
