摘要：

A critical comparison is made between the angle-resolved-photoemission-spectroscopy- (ARPES-) derived spectral function and scanning tunneling microscopy (STM) studies of Friedel-like oscillations in Bi2Sr2CaCu2O8+delta (Bi2212). The data can be made approximately consistent, provided that (a) the elastic scattering seen in ARPES is predominantly small-angle scattering and (b) the "peak" feature seen in ARPES is really a dispersive "bright spot," smeared into a line by limited energy resolution; these are the bright spots which control the quasiparticle interferences. However, there is no indication of bilayer splitting in the STM data.
