than pure silicon, or negatively doped, i.e. the added substance has an
excess of valence electrons. In either case, electric current can flow
under the right conditions.
A strong charge applied to the central positively doped layer in the
transistor allows a current to flow between the two negatively doped

flow. In this way the transistor acts like a switch, allowing current to
flow or no ...
