Expert Answer:

N-type semiconductor materials are doped with elements which have spare electrons in their outer shells. This gives N-type silicon free electrons (which are negatively charged particals) which can move about at will - with the potential to create current.

P-type semiconductor materials are doped with elements that have too few electrons in their outer shells. Therefore the opposite of electrons - holes - are free to move about within the material - with the potential to create current.
