The p-n junctions are elementary building blocks of semiconductor electronic devices. As the name suggest it is a junction between two types of semiconductor materials the p-type and the n-type. The p-type is the positive side of junction and n-type is the negative side. The p-type consists of excess holes (missing electrons) and n-type consists …
