In superconductors, the bosons are the pairs of bound electrons that form at the Fermi surface. 在超导体中,玻色子是在费密表面形成的束缚态电子对。
The angle_resolved photoemission ( ARPES ) is a powerful experiment method to study the surface electronic structure of crystals, such as energy bands, Fermi surface, and many_body interaction. 角分辨光电子能谱(ARPES)是研究晶体表面电子结构,如能带,费米面(FS),以及多体相互作用的重要工具。
Magnetic breakdown occurs at the gap between the spin-up and spin-down sheets of the Fermi surface. 磁击穿发生在自旋向上和向下的两片Fermi面之间。
And because superconducting electron pairs only occur near the Fermi surface, in the vicinity of the images of Fermi surface, the study on this issue is very important. 由于超导凝聚电子对一般只发生在费米面(FS)附近,费米面(FS)的图像的研究,对于这个问题的研究有很重要的意义。
The quantitative results about shift of Fermi surface, widening of energy band width and varying of atomic valence of each crystal site are given. 给出了高压下费米面(FS)移动、能带展宽和各晶位原子价变化的定量结果。
