The main scattering mechanism is ionized impurity scattering and acoustical phonon scattering . the experimental results show that the high quality of zno . al films were obtained 实验结果表明利用电子束蒸发技术制备的zno : al薄膜材料,具有较好的结构及光电特性。
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; not dissimilar to an electron encountering an electric field.
