Pb $_{9}$ Cu(PO $_{4}$ ) $_{6}$ O is a charge-transfer semiconductor

Lorenzo Celiberti, Lorenzo Varrassi, Cesare Franchini

By means of density functional theory and constrained random phase approximation we analyze the bandstructure of Pb $_{9}$ Cu(PO $_{4}$ ) $_{6}$ O (named LK-99). Our data show that the lead-ph…
