why n type semiconductor is electrically neutral?

why n type semiconductor is electrically neutral?
An n-type material by itself has mainly negative charge carriers (electrons) which are able to move freely, but it is still neutral because the fixed donor atoms, having donated electrons, are positive.
How is a sample of N-type semiconductor electrically neutral?
In a sample of N - type semiconductor, the number of conduction electrons is high compared to the number of holes. But the semiconductor material is electrically neutral. This is because, the charge of excess electrons are just equal and opposite to the charge of ionized immobile cores of the lattice. Dec 13, 2013

Why a P-type semiconductor crystal is electrically neutral although NH ne?
An intrinsic semiconductor has same number of holes and electrons while in a p - type semiconductor the number of holes is greater than the number of electrons. Each hole is associated with a nearby negative-charged dopant ion, and thus semiconductor remains electrically neutral as a whole. Jun 4, 2014

Why n-type and p-type semiconductors are electrically neutral?
As the charge on the donor ion is equal and opposite to the charge of the electron, the crystal itself remains electrically neutral. With the same reasoning, p - type semiconductor is also electrically neutral. Jun 4, 2014
