AI 中文摘要
本文考察了费米面几何中的精细特征,如近圆柱形或近抛物面形条带或局部平坦区域,对金属电子(主要是电磁输运)特性的影响。研究表明,在一定条件下,这些特征可能显著改变常规正常金属或具有金属导电性的层状结构对高频外部扰动的响应方式。所考虑的所有效应似乎对扰动传播方向和/或外部磁场方向非常敏感。文中讨论了观察所述效应的实验可能性。
英文摘要
Fine features in the Fermi surface geometry, such as nearly cylindrical or nearly paraboloidal strips or local flattenings, are examined as regards their effect on the electronic, mainly galvanomagnetic, properties of metals. It is shown that under certain conditions, these features may significantly change the way a conventional normal metal or a layered structure with metallic conductivity responds to high- frequency external disturbances. All of the effects considered appear to be very sensitive to the disturbance propagation direction and/or to that of the external magnetic field. Experimental possibilities of observing the described effects are discussed.
