WebJul 5, 2016 · This research paper is on Density Functional Theory (DFT) within Local Density Approximation. The calculation was performed using Fritz Haber Institute Ab-initio Molecular Simulations (FHIAIMS) code based on numerical atomic-centered orbital basis sets. WebThe total density of states (TDOS) at energy E is usually written as. N(E) = ∑ i δ(E − ϵi) (4.5.1) where the ϵi denote the one-electron energies. So the integral of N(E) over an energy interval E1 to E2 gives the number of one-electron states in that interval. Usually the δ -functions are broadened to make a graphical representation ...
