Recently we have used spectroscopic mapping with the scanning tunnelingmicroscope to probe modulations of the electronic density of states in singlecrystals of the high temperature superconductor Bi2Sr2CaCu2O8+d (Bi-2212) as afunction of temperature [C. V. Parker et al., Nature (London) 468, 677 (2010)].These measurements showed Cu-O bond-oriented modulations that form below thepseudogap temperature with a temperature-dependent energy dispersion displayingdifferent behaviors in the superconducting and pseudogap states. Here wedemonstrate that quasiparticle scattering off impurities does not capture theexperimentally observed energy- and temperature-dependence of thesemodulations. Instead, a model of scattering of quasiparticles from short-rangestripe order, with periodicity near four lattice constants (4a), reproduces theexperimentally observed energy dispersion of the bond-oriented modulations andits temperature dependence across the superconducting critical temperature, Tc.The present study confirms the existence of short-range stripe order inBi-2212.
