Question

How may "n" and "p" type semiconductor materials be combined to form a diode?

Answer 1

wow wish i knew wat u were talkin about

Answer 2

The short version is a piece of N doped silicon and a piece of P doped silicon are diffused together. Longer versions at

Answer 3

Generally one "n" type and one "p" type semiconductors combined to form a diode.

Answer 4

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.
