WebThe answer has to do with the existence of nesting vectors in the materials' Fermi surfaces. The concept of a nesting vector is illustrated in the Figure for the famous case … In physics, a wave vector (or wavevector) is a vector used in describing a wave, with a typical unit being cycle per metre. It has a magnitude and direction. Its magnitude is the wavenumber of the wave (inversely proportional to the wavelength), and its direction is perpendicular to the wavefront. In isotropic media, … See more For this article, the terms wave vector and angular wave vector are used with distinct meanings to avoid confusion. Here, the wave vector is denoted by k and the wavenumber by k = k , and the angular wave vector is … See more In solid-state physics, the "wavevector" (also called k-vector) of an electron or hole in a crystal is the wavevector of its quantum-mechanical wavefunction. These electron waves are not ordinary sinusoidal waves, but they do have a kind of envelope function which … See more • Plane wave expansion • Plane of incidence See more The direction in which the wave vector points must be distinguished from the "direction of wave propagation".
