To gain insight into the electronic properties of PrFe 4 P 12 filled skutterudite, band electronic structure calculations, total and projected density of states, crystal orbital overlap population and Mulliken population analysis were performed. The energy bands yield a semi-metallic behavior with a direct gap (at Γ) of 0.02 eV. Total and Projected Density of States provided information of the contribution from each orbital of each atom to the total Density of States. Moreover, the bonding strength between some atoms within the unit cell was obtained. Mulliken Population Analysis suggests ionic behavior for this filled skutterudite.
