本文研究了层厚无序超晶格的电子波函数特征,发现其既有扩展的一面,又有局域的一面。文中具体给出了局域长度的数值计算结果。The wave functions of electrons in superlattices with random layer thicknesses are studied. They are localized in the direction perpendicular to the layers characteristic of one-dimensional systems and extended in the plane of the leyers. Numerical results of computation of localization lengths are given.
