A related concept is that of the irreducible Brillouin zone, which is the first Brillouin zone reduced by all of the symmetries in the point group of the lattice (point group of the crystal). plotting individual points matlabWebThe bulk of the question should define "gamma point" (k=0), and "bandstructure view" (you mean band theory) "of dispersion relation" (you mean the E (k) curve for an electron). A moving electron has more energy than an electron at rest, so it obviously takes less energy to move it to a higher band. Does this answer the question? princess nina jewelleryIn solid-state physics, the electronic band structure (or simply band structure) of a solid describes the range of energy levels that electrons may have within it, as well as the ranges of energy that they may not have (called band gaps or forbidden bands). Band theory derives these bands and band gaps by examining the allowed quantum mechanical wave functions for an electron in a large, periodic lattice of atoms or molecules.
