We calculated the band structure and projected density of states (pDOS) with HSE-06 and found that Sc2C is a semiconductor with a 0.305 eV indirect band gap and a 0.476 eV direct band gap (Figure ). The pDOS was calculated with a dummy atom of no charge to illustrate the contribution of the electride states to the overall density. This shows that the electride electron density mirrors that of the scandium and that the scandium orbitals are hybridizing with the electride electron density in the same way that has been observed in Y2C and Hf2S .
