Question

Matlab code n type semiconductor current

Answer 1

N-type material has many conduction band electrons. If a voltage is connected across N-type crystal free electrons will move towards the positive terminal. If we have a battery and we have it connected N-type material those free electrons, remember current flow is negative to positive, those free electrons are going to be attracted to the positive terminal. As electrons are moved from one atom towards the positive terminal a hole is left behind allowing more electrons to shift toward the source voltage. Some of the valence electrons will also be moving. There will be holes created, electrons will be coming through here, some of them will move as free electrons, others will move through holes. There are more electrons than holes, as in the case in of N material, so current movement is electron movement.
