Abstract: Abstract Direct current (DC) dark conductivity, (σ) measurements have been carried out in thin films of N‐isopropylcarbazole/polycarbonate mixtures (NIPC/PC) for relative weight ratio (x) in the range 2 to 80% by weight of NIPC in PC at room temperature. The experimental results suggest a non‐percolative transport in the concentration range explored. In the range 20 to 80%, a hopping character and power law dependence σ ∼ (x − xc)3 is found with xc = 0.16. In the range 2 to 20% these relations are masked by t…
