學(xué)習(xí)abinit遇到的問題,關(guān)于表面能的計(jì)算
|
|
今天學(xué)習(xí)abinit的教程4.4,學(xué)習(xí)計(jì)算100晶面的表面能,看了輸入文件,但是不明白輸入文件那個地方定義了要計(jì)算的是100的表面能。 #Definition of the k-point grids ngkpt 4 4 4 nshiftk 2 shiftk 0.5 0.0 0.5 0.0 0.5 0.5 #Definition of the unit cell acell 3*7.50559090E+00 # Lattice parameters of bulk aluminum rprim 0.5 -0.5 0.0 # These values will define a cell with two atoms, 0.5 0.5 0.0 # non-primitive, with a different orientation 0.0 0.0 1.0 # than the primitive cell. chkprim 0 # This input variable allows to use non-primitive unit # cells. Please, do not use it in other cases, # you might miss a primitive cell, faster to handle. #Definition of the atom types ntypat 1 # There is only one type of atom znucl 13 # The keyword "znucl" refers to the atomic number of the # possible type(s) of atom. The pseudopotential(s) # mentioned in the "files" file must correspond # to the type(s) of atom. Here, the only type is Aluminum #Definition of the atoms natom 2 # There are two atoms in this doubled cell typat 2*1 # These atoms are of type 1, that is, Aluminum xred # This keyword indicate that the location of the atoms # will follow, one triplet of number for each atom 0.0 0.0 0.0 # Triplet giving the REDUCED coordinate of atom 1. 0.5 0.5 0.5 # Triplet giving the REDUCED coordinate of atom 2. |
