Si bandstructure - VASP Wiki
Calculation of the bandstructure for Si within DFT+HF. The bandstructure in VASP can be obtained following three different procedures. The standard procedure (procedure 1), applicable at PBE level, is also described in Fcc Si bandstructure example. Within Hybrid functional theory it is possible to plot bandstructure using procedure 2 or 3.
Electronic band structure - Wikipedia
In 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).

2023年4月27日 · Si (band structure) VASP中能带结构计算流程与态密度相同，具体不同点如下； 1. scf自洽计算. 与态密度dos计算中的scf自洽计算完全相同。 2. 能带结构非自洽计算. 能带计算与scf计算中的输入文件对比如下： POTCAR：不需更改，与scf计算相同。 POSCAR：不需更 …
2.1.5 Band Structures and Standard Representations - Technische …
Si is an indirect semiconductor because the maximum of the valence band (at G) does not coincide with the minimum of the conduction band (to the left of X). There is, however, a lot more information encoded in this diagram, as we will see later.
mp-149: Si (cubic, Fd-3m, 227) - Materials Project
Si is diamond structured and crystallizes in the cubic Fd-3m space group. The structure is three-dimensional. Si is bonded to four equivalent Si atoms to form corner-sharing SiSi4 tetrahedra. All Si–Si bond lengths are 2.37 Å.
Bandstructure of Si in GW (VASP2WANNIER90) - VASP Wiki
Calculation of the bandstructure of Si in GW using the VASP2WANNIER90 interface. Mind : The procedure to compute bandstructure in GW using V2W is almost identical to the corresponding HSE one described in Si bandstructure .
Fcc Si bandstructure - VASP Wiki
You may use the CHGCAR file of the fcc Si DOS example. CALCULATION. To copy the self-consistent charge density of example fccSidos to your current working directory, type: cp ../fccSidos/CHGCAR . You must do this otherwise VASP can not read the CHGCAR and will terminate. To plot the bandstructure use p4vasp:

Band structure of Si at 300 K. E g = 1.12 eV E L = 2.0 eV E X = 1.2 eV E so = 0.044 eV E Γ1 = 3.4 eV E Γ2 = 4.2 eV
Silicon Band Structure - lampz.tugraz.at
The valence bands consist of a light hole band, a heavy hole band, and a split-off band. All three bands have a maximum at $k=0$. The light hole band and the heavy hole band are degenerate at $k=0$ while the energy of the split-off band is $E_{so}$ lower at $k=0$.
6.3 Silicon Band Structure Models - TU Wien
The simplest model of the silicon band structure is based on the effective mass. If the band structure is known, the energy wave vector relation in one dimension can be expanded in a Taylor series as
