You can use a tool called SeeK-path to get the high-symmetry points for your structure using the POSCAR file as an input. For instance, for graphene, your POSCAR could be C 1.0 1.22800000 -2.12695839 0.00000000 1.22800000 2.12695839 0.00000000 0.00000000 0.00000000 20. 2 direct 0.00000000 0.00000000 0.25000000 0.33333333 0.66666667 0.25000000 ...

The short answer is that this is a metal because of the following reasons: An insulator or semiconductor features a bandgap between the occupied and the unoccupied states. For a temperature of 0K the Fermi energy discriminates between these two different occupations. This means the bandgap has to be around the Fermi level. A bandgap means that there are no ...

I've never done this before but here is my guess of how you can do it. If the numbers you posted are the unit cell axes vectors with a vector for each column then their direct matrices are. $$\tag{1}\mathbf{A} = \begin{bmatrix}3.31 & 0.00 & 0.00 \\ 0.00 & 10.47 & 0.00 \\ 0.00 & 0.00 & 4.37\end{bmatrix}...

Here I show the typical calculation flow of GW in VASP: a DFT ground-state calculation. obtain DFT virtual orbitals GW calculation including LWANNIER90 TAG Compute Wannier functions and Obtain bandstructure by Wannier interpolation. PS1: use POTCAR like [XXX_GW]. PS2: If you want to include spin-orbit coupling, just add the following tags: LSORBIT=.TRUE....
