Electronic signals travel approximately one foot per nsec.
A semiconductor type in which the density of holes in the valence band is exceeded by the density of electrons in the conduction band. N-type behavior is induced by the addition of donor impurities, such as arsenic or phosphorus, to the crystal structure of silicon. See also acceptors , donors , doping and impurities .
