In　this　paper,　we　focus　on　studying　the　meron　defects　on　checkerboard　lattice　based　on　two-band　structures.　Merons　are　two-dimensional　point　defects,　whose　topological　charges　give　the　evaluations　of　the　Chern　numbers　of　the　two　bands.　We　first　reproduce　the　results　of　a　previous　model　from　the　defect　perspective.　Then,　the　model　is　extended　to　attain　the　higher　Chern　number　systems.　We　show　that　the　model　can　achieve　C=±3　structures　through　analyzing　the　charges　of　the　merons.　The　energy　spectrum　also　reveals　that　three　gap-closed　states　appear　on　the　edges.　©　2025　The　Authors
