Electronic Structure of LK-99
Summary: A recent study suggests that Pb9Cu(PO4)6O, also known as LK-99, might be a room-temperature superconductor at ambient pressure. Density-functional theory calculations show lattice parameters and volume contraction similar to experiments. The electronic structure indicates a possible Mott or charge transfer insulator, which, if doped, could support flat-band superconductivity or a correlation-enhanced electron-phonon mechanism.
