How may “n” and “p” type semiconductor materials be combined to form a diode?
One n type and another one p type when combining them there are two ways to do this (1) to make it n-p junction An n-p junction will only allow current to flow in one direction. The electrons from the n-type material can pass to the right through the p-type material, but the lack of excess electrons in the p-type material will prevent any flow of electrons to the left. (2) to make it p-n junction.In a p-n diode, conventional current can flow from the p-type side (the anode) to the n-type side (the cathode), but cannot flow in the opposite direction.
