Abstract

We have implanted a number of insulating polymer (PET) thick films with fluences in the range 1 × 1013 to 5 × 1017 ions/cm2 in order to induce electronic activity. Finite electrical conductivities were obtained for fluences as low as 3 × 10 15ions/cm2. The resistivity for these implanted materials increases with decreasing temperature demonstrating highly disordered or semiconducting behavior. Hall effect measurements confirm this result and indicate negatively charged carriers with a carrier density of 1.44 × 10 17cm -3 for an implant dose of 1 × 1017 ions/cm2. The conductivities also seem to be dependent on the implanted ion species. We believe this material will be useful as an accurate temperature sensor near room temperature.
