Question

k y do we dope a semiconductor with a group 5 and group 3 element? y do not we dope it with group 6?

Answer 1

You start with a substrate of a semi-conductor, group 4, when you dope with group 5 you add electrons and when you dope with group 3 you add holes, so the theory goes.

Answer 2

that was not my question kenl but i wanted to knw y dnt we use to make n type with group 6

Answer 3

Group 6 is basically stable when compared to group 3 and 5, and doesn't exhibit the proper characteristics. As I said you have a substrate of group 4, 4 electrons out of a full 8, dope with group 5, one more electron than group 4, or dope with group 3, one less electron than group 4. These are the only elements that actually have the characteristic that represent semi-conductor theory.

Answer 4

We make p type and n type semiconductor from silicon by doping those element to get characteristics exhibiting in the diode and transistor such as biasing switch and rectifying .
