==== Merging the P-type semiconductor and the N-type semiconductor ====

Now that we understand the concept of P and N type semiconductors, the concept of holes and electrons. Let us go one step further to merge the P-type and N-type and understand how electric fields are created.

When the n and p materials are in contact, free electrons in the n-type material adjacent to the many holes in the p-type material at the junction will jump into the p-type material, filling the holes. This charge transference process happens rapidly along the dividing line (junction), sending huge numbers of electrons to 'the p-type side and holes to the n-type side.
