Energies This input specifies a list of energies for which the density of states should be calculated. The list is generated from the number of energy points, the starting value, and the end value. For instance, the values 11, 0, and 1 creates the list [0, 0.1, 0.2, 0.3, 0.4, 0.5, 0.6, 0.7, 0.8, 0.9, 1.0]. Local Density of StatesÖеÄQuantum Numbers The transverse k-point, in scaled coordinates, for which the local density of states is to be calculated. In the case of polarized computations, you also need to specify the spin. Transmission EigenvaluesÖеÄQuantum Numbers Sequence of quantum numbers (k-points for A and B) and the spin at which the transmission eigenvalues should be calculated. ÔÚEigenstates£¨atk˵Ã÷Ê飩ÖÐQuantum numbers An integer n for an unpolarized molecule, an integer pair (n,s) for polarized molecules, an integer pair (n,k) for unpolarized bulk systems, or an integer triplet (n,k,s) for polarized bulk systems. Here n is the energy level quantum number (non-negative integer), s is the spin state, and k is the fractional k-point (a sequence of 3 numbers).
