WebDOS Enabled True Energies 500 Min -0.35 Max 1.05 File plotfile End. According to this example, DOS values will be generated in an equidistant mesh of 500 energy values, ranging from 0.35 a.u. below the Fermi level to 1.05 a.u. above it. All information will be written to a file plotfile. The density of states appears in many areas of physics, and helps to explain a number of quantum mechanical phenomena. Calculating the density of states for small structures shows that the distribution of electrons changes as dimensionality is reduced. For quantum wires, the DOS for certain energies actually becomes higher than the DOS for bulk semiconductors, and for quantum dots the electrons beco…
