Electronic band structures
WebThe GW method is a standard method to calculate the electronic band structure from first principles. It has been applied to a large variety of semiconductors and insulators but less often to metallic systems, in particular, with respect to a self-consistent employment of the method. In this work, we take a look at all-electron quasiparticle self-consistent GW … http://www.phys.lsu.edu/~jarrell/COURSES/SOLID_STATE/Chap7/chap7.pdf

WebJul 20, 2024 · Electronic valence band structure of SrTiO 3 along Γ − R obtained from calculations in the primitive unit cell with static nuclei at equilibrium (red) and in 5 × 5 × 5 supercells (gray). As (a) exemplifies, the electronic dispersion ε ( k ) obtained in the primitive unit cell along Γ − R is “folded” into a reduced Brillouin zone ... WebThe electronic band structure of the lead salt compounds PbTe, PbSe and PbS is characterised by their small and direct energy gap less than 410 meV at the L-points of the Brillouin zone [44,45,52,53]. As a result, photons can be directly absorbed or emitted at the band edges. The conduction and valence bands are nearly mirror symmetric with ...
