Projected density-of-states

WebI understand the basics of the density functional theory method: each orbital of each substance is described by basis functions, the concept of electron density ρ is introduced and there is a one-to-one correspondence between the wave functions and the introduced electron density. WebThe PDOS is a projected density of states. In the context of VASP this means site-projected DOS, where the information about the different contributions of the different orbitals is computed.
