Abstract
We study the effects of varying the preimplant film thickness and implant temperature on the electrical and superconducting properties of metal-mixed ion-implanted polymers. We show that it is possible to drive a superconductor-insulator transition in these materials via control of the fabrication parameters. We observe peaks in the magnetoresistance and demonstrate that these are caused by the interplay between superconductivity and weak localization in these films, which occurs due to their granular structure. We compare these magnetoresistance peaks with those seen in unimplanted films and other organic superconductors and show that they are distinctly different.
