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 … Witryna2 dni temu · Unlike conventional lattice doping with impurity atoms, it is challenging to achieve doping in nanoscale materials due to the limited physical space. ... The frozen mobile ions provide ...
