| Abstract | We used angle-resolved photoemission spectroscopy to study the shadow Fermi surface in one layer Bi2Sr1.6La0.4CuO6 + delta and two layer (Bi,Pb)2Sr2CaCu2O8 + delta. We find the shadow band to have the same peak width and dispersion as the main band. In addition, the shadow band/main band intensity ratio is found to be binding-energy independent. Consequently, it is concluded that the shadow bands in Bi-based HTSC do not originate from atiferromagnetic interactions, but have a structural origin. ©2004 The American Physical Society |
