Web(a) An n-type semiconductor with electrons moving left to right through the crystal lattice. (b) A p-type semiconductor with holes moving left to right, which corresponds to electrons moving in the opposite direction. Current flow in a P-type semiconductor is a little more difficult to explain. WebJun 18, 2016 · \$\begingroup\$ n-type does not have any extra electrons. It has the same number of negative electrons as positive static atomic nuclei. What makes it "n-type" is that some electrons are not bound to static nuclei and thus can move freely (and thus, act as charge carriers and conduct current). The same logic applies to p-type as well. …

Webside has excess holes while n-type has excess electrons. And we also know that opposite charges attract each other. ... electrons and holes do rush towards the opposite side and get neutralized, but very soon this gives rise to charged ions at a small region near the border or the junction.
