Description

The single layered superconductor Bi2-yPbySr2-xLaxCuO6+δ (x=0.4) around optimal doping has been investigated by scanning tunneling microscopy (STM). Continuously changing the amount of lead showed a fascinating structural development and revealed new modulations in the BiO layer. Special attention has been given to the ''inhomogeneous'' background modulation. It is suggested that this background is not just caused by electronic reasons, but has structural origin. Because of the short range of this modulation it could influence the electronic structure of the CuO2 plane and the charge transfer between this plane and the carrier reservoir (BiO-SrO). In this context the question arises if a ''good'' and a ''bad'' background with respect to superconductivity exists
