Description: compute the bandstructure in fcc Si along L-Γ-X-U and K-Γ

Mind: For this calculations you need the CHGCAR file of the fcc Si DOS example.


Task

Input

System = fcc Si 
ICHARG = 11 #charge read file
ENCUT  =    240
ISMEAR = 0; SIGMA = 0.1;
LORBIT = 11

KPOINTS

k-points for bandstructure L-G-X-U K-G

CHGCAR

This calculation needs a converged charge density as input (ICHARG=11). You may use the CHGCAR file of the fcc Si DOS example.
