 Dear everyone,
         Does anyone know how to calculate the d-band center of transition metals? According to the Friedel Model, the d-band is treated as a rectangular density of states centred on energy a with width W . However, the PDOS we obtained from calculation is usually irregular with sharp peaks, not a rectangular. Then comes to the question:  how to decide the range of d-band energy by applying rectangular model ?  how to get the d-band center from PDOS?
         Thanks inadvance.
