摘要：

We identify a disorder induced mobility edge E(C) in the system Bi-2212+Y/Ca. The substitution 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 either be reached by Y3+ or Ce4+ substitution and depends only on the total carrier density.
