In quantum mechanics, ionized impurity scattering is the scattering of charge carriers by ionization in the lattice. The most primitive models can be conceptually understood as a particle responding to unbalanced local charge that arises near a crystal impurity; similar to an electron encountering an electric field. This effect is the mechanism by which doping decreases mobility. In the current quantum mechanical picture of conductivity the ease with which electrons traverse a crystal … WitrynaThe time when anode passivation firstly occurs shortened significantly in solution containing 0.596 mol·dm-3 of Ni2+ ions as impurity, and shortened somewhat in …
