Abstract:：
Organic mixed ionic electronic conductors (OMIECs), in particular conducting polymers, continue to attract intense research efforts, motivated by emerging applications in bioelectronic, neuromorphic, energy storage and thermoelectric devices. These materials are typically doped in their bulk to very high carrier densities on the order of 1020-1021 cm-3 to achieve metallic conduction. They exhibit fascinating non-linear, many-body and non-equilibrium transport phenomena in this regime, that could be exploited in these applications, but whose scientific origin remains poorly understood. Another approach to achieving metallic conduction is to extend the conjugation pathways to two-dimensions; my group has been particularly interested in metallic, two-dimensional conjugated metal organic frameworks (MOFs), in which organic ligands and transition metal ions, such as copper or nickel form extended coordination-bonded frameworks. In the talk I will give an overview of our present understanding of the charge transport physics of OMIECs and conjugated MOFs.
