WebApr 20, 2016 · For example, I have calculated band structure and DOS of doped graphene but they are not consistent. I have used ISMEAR -5 with dense k-grid in vasp code. Even I have found that DOS shows band gap ... WebMar 26, 2024 · VASP specific parameters of importance: PREC : should be at least normal, but high or accurate are also possible. EDIFF : a value of 1. 0E-6 to 1.0E-8 are reasonable for small systems. Note that this value should be much smaller than the accuracy you wish to obtain. NSW = 0; IBRION = -1 : It should be static calculations.
