Electronic Structure of Disordered Materials,It has been known since the work of Bloch (1928) that there are universal features in the electronic structures of crystals. The most important of these are energy bands separated by gaps, crystal momentum as a good quantum number, and the form of the wave function; they provide the conceptual foundations of much of solid state physics.暖昧关系 发表于 2025-3-25 19:32:12
Die Finanzierung durch Mitgliedsbeiträgeone certainly was that crystallography offered the physicist a ready-made formalism describing the symmetry properties of periodic crystal lattices. Only the glasses presented too much technical interest to be completely pushed aside.逃避现实 发表于 2025-3-25 23:40:45

Die Kosten der Parteiendemokratiemetry arguments based explicitly on the existence of long-range order. Indeed, this is one of the few properties of crystals which cannot be accounted for on the basis of short-range order alone: If the long-range order is destroyed, the sharp structural detail, which is typical for crystals, disappObedient 发表于 2025-3-26 18:43:55

Furthermore, the theoretical difficulty of calculating the distribution of electronic states and their transport properties in disordered structures and the resulting need for simplifying approximations provide the theoretical expressions with considerable flexibility.
