We identify a disorder induced mobility edge E c in the system Bi-2212+Y/Ca. The ~uhstitution shifts the Fermi energy below E c and causes a superconductor-insulator transition. In the insulating state charge transport happens by Variable-Range-Hopping (Shklovski-Efros case). The transition can eith
Structural refinements of the new compounds Bi2Sr3\_ xYxCu208 + y in the range of x that gives insulating rather than superconducting behaviour (x~ 0.6 and 1.0) have been obtained from single crystal X-ray and neutron powder diffraction data. Results indicate oxygen nonstoichiometry and suggest cond
