摘　　要：金属是有费米面的固体,费米面的形状和大小对材料的热学、电学、磁学等性质有重要影响.本文用第一性原理方法计算了几种常见金属的能带结构和费米面以及半导体材料硅和锗导带底的等能面,并将能带与费米面和等能面进行对应分析,为在三维倒空间理解费米面及其与能带的关系提供了参考.A metal is a solid with a Fermi surface.The shape and size of Fermi surfaces have important influences on the thermal,electric,and magnetic properties of materials.Here first-principle calculations have been performed to study the band structures and Fermi surfaces of several frequently-used metals as well as the iso-energy surfaces near the conduction band minima of semiconductors Si and Ge,based on which the band structures and Fermi surfaces are corelated and analyzed.This work provides references for understanding the Fermi surfaces and energy bands in the three-dimensional reciprocal space.
