%X we have measured transport properties at low temperatures for the granular sm1.82ce0.18cuo4-d samples belonging to the family of electron-doped superconductors. the effect of applied electrical current on the resistive behavior is investigated. the experimental data are analyzed using a modified form of the theory for a field-tuned superconductor-insulator transition in 2d superconductors. the results suggest a possible electrical-current driven superconductor-insulator transition.
