When you join a p-type semiconductor with an n-type semiconductor to form a p-n junction, holes initially flow from the p-type material into the n-type material, and electrons flow in the opposite direction. Why? a) There is an electric field because of the positive charge in the p-type material and the negative charge in the n-type material. b)Each diffuses into the region where it is at lower concentration. c)The n-type material is at lower potential. d)The n-type material is at...

4. A p-type semiconductor has positive charge carriers but is electrically neutral. Similarly an n-type semiconductor has negative charge carriers but is electrically neutral. When they are put in contact (making a diode), statistical forces cause some of the charge carriers to migrate to the opposite semiconductor. The charge carriers move until an E-field is created to stop the migration. This E-field creates a depletion region near the junction where there are no charge carriers. If a forward voltage is...
