论文摘要
压电材料的变形导致传导效应，这是由于两个贡献所致：离子核的相对位移和所谓的轨道极化。这项工作致力于在包含连续随机系统的广义环境中著名的国王史密斯和范德比尔特公式的严格推导。
Deformations in piezoelectric materials lead to conduction effects, which are due to two contributions: the relative displacements of the ionic cores, and the so-called orbital polarization. This work is devoted to the rigorous derivation of the celebrated King-Smith and Vanderbilt formula for orbital polarization in a generalized setting that includes continuous random systems among others.
