Question

what is p n junction diode​

Answer 1

A p-n junction diode is a basic semiconductor device that controls the flow of electric current in a circuit. It has a positive (p) side and a negative (n) side. ... To make a p-n junction diode, a different impurity is added to each side of a silicon semiconductor to change how many extra holes or electrons are present.
