Pb substitution in Bi2212 reduces the incommensurate modulation vector and suppresses superstructure intensity until it nearly vanishes at x=0.8, with ARPES superstructure bands showing strong photon-energy dependence.

Evolution of Incommensurate Superstructure and Electronic Structure with Pb Substitution in (Bi$_{2-x}$Pb$_{x}$)Sr$_2$CaCu$_2$O$_{8+\delta}$ Superconductors
Pb substitution in Bi2212 reduces the incommensurate modulation vector and suppresses superstructure intensity until it nearly vanishes at x=0.8, with ARPES superstructure bands showing strong photon-energy dependence.
