The mechanisms of current flow in polymethyl methacrylate (PMMA) doped with molecular iodine were investigated. Analysis of the current-voltage characteristics revealed a sequential change in conductivity modes with increasing voltage: ohmic mode, space-limited current mode (SCLC), and trap-limited current mode (TCLC). It was established that these modes are associated with the formation of polyiodide complexes in the polymer matrix, which create trap states of varying depths in the band gap between the HOMO and LUMO levels. The obtained results demonstrate a fundamental difference between the charge-transport mechanisms in iodine-doped PMMA and classical band transport in crystalline silicon.
