Answer:
The p-n junction is a region formed when a p -type semiconductor material is joined to an n-type semiconductor material
Explanation:
The p type semiconductor has holes as its majority charge carriers making it positively charged while the n –types has an overall negative charge. At the junction the holes move towards the electron until such a time when there is a balance in charges from both materials, which leads to the formation of the depletion zone as shown in the attachment below
