The density of states (Density of States, DOS) is defined as the allowed energy levels within the unit energy.The total density of states is decomposed according to the angular momentum,getting the local density of states(Local density of states.LDOS). In general the method to produce plane wave is to do ASA (atomic sphere approxiamtion),similarly projecting a given radius onto each atom in real space.If the LDOS range is specified as HOMO's energy range, the HOMO atomic orbital component is what we seek.LDOS and orbital component are in cross relation. ¹©LZ²Î¿¼¡£ |
