IRG 1 seeks to establish fundamental structure-function relationships that govern the transport of charge carriers (electrons and holes), excitons (electron-hole pairs), and energy (vibrational or electronic) through multiscale materials with a particular focus on organic-inorganic interfaces within these materials and devices. By manipulating both the nanostructure of the building blocks and the structure of the interfaces between them through synthetic and fabrication processes, the group will decouple traditionally coupled fluxes and produce materials with combinations of properties that are not found in conventional macroscopic materials. The research requires a highly interactive, interdisciplinary team approach; the research activities and goals harness the group’s depth of expertise in synthesis and structural characterization—employing methodologies ranging from X-rays to ultrafast optical spectroscopies to scanning probes—and in measurements and modeling of transport and device characteristics.
