Abstract

Manipulating the gap Cuprate superconductors typically have a large amount of spatial inhomogeneity, partly stemming from the inhomogeneity of the chemical doping process. In particular, the size of the spectroscopic gap can vary widely across a single sample. Massee et al. used the tip of a scanning tunneling microscope to manipulate atoms on the surface of a member of the Bi 2 Sr 2 CaCu 2 O 8+x cuprate family. Moving bismuth atoms up or down caused adjacent atoms to shift laterally, leading to reversible local changes in the size of the gap. It is expected that the technique can be used to probe the influence of the local lattice on the electronic states of other correlated materials. Science , this issue p. 68
