Abstract
The study of insulator-metal transitions (IMTs) can provide insight into the dynamical properties of complex, disordered systems.1 Specifically, the subtleties of phenomena like carrier localization and transport in systems such as conducting polymers and colloidal metal films can be probed and elucidated. This paper reports the results of optically excited carrier dynamics near the IMT in a series of thin films composed of 12-nm colloidal gold particles and a series of thin polyaniline (PANI) films of varying conductivity.
