找到了这篇文章,用VASP算的:PHYSICAL REVIEW LETTERS 126, 076401 (2021)摘要:Supercell models are often used to calculate the electronic structure of local deviations from the idealperiodicity in the bulk or on the surface of a crystal or in wires. When the defect or adsorbent is charged, ajellium counter charge is applied to maintain overall neutrality, but the interaction of the artificially repeatedcharges has to be corrected, both in the total energy and in the one-electron eigenvalues and eigenstates.This becomes paramount in slab or wire calculations, where the jellium counter charge may inducespurious states in the vacuum. We present here a self-consistent potential correction scheme and providesuccessful tests of it for bulk and slab calculations
