五、POTCAR

POTCAR文件简介

PAW_PBE O 08Apr2002
6.00000000000000
parameters from PSCTR are:
SHA256 = 818f92134a0a090dccd8ba1447fa70422a3b330e708bb4f08108d8ae51209ddf O/POTCAR

VRHFIN =O: s2p4
LEXCH = PE
EATOM = 432.3788 eV, 31.7789 Ry
TITEL = PAW_PBE O 08Apr2002
LULTRA = F use ultrasoft PP ?
IUNSCR = 1 unscreen: 0-lin 1-nonlin 2-no
RPACOR = 1.200 partial core radius
POMASS = 16.000; ZVAL = 6.000 mass and valenz
RCORE = 1.520 outmost cutoff radius
RWIGS = 1.550; RWIGS = 0.820 wigner-seitz radius (au A)
ENMAX = 400.000; ENMIN = 300.000 eV
ICORE = 2 local potential
LCOR = T correct aug charges
LPAW = T paw PP
EAUG = 605.392
DEXC = 0.000
RMAX = 1.553 core radius for proj-oper
RAUG = 1.300 factor for augmentation sphere
RDEP = 1.550 radius for radial grids
RDEPT = 1.329 core radius for aug-charge
……后面的数值部分太长省略不写了,感兴趣的可以自己打开一个POTCAR文件看一下
