During the first ATUMS phase we exploited the recently discovered semiconducting material SnIP and acquired decent knowledge on its utilization in functional hybrid materials. We showed that SnIP can successfully be incorporated in different standard polymers like polyethylene oxide (PEO), poly(3,4-ethylenedioxythiophene)-poly(styrenesulfonate) (PEDOT:PSS), or polyvinylidenfluorid (PVP) as well as in TiO2 nanotube membranes. Due to the beneficial flexibility of SnIP, which is caused by the double helical crystal structure, such hybrids are potential candidates for flexible electronic devices (the polymer hybrids) or water splitting catalysts, solar cell components or sensors.
We expect to additionally influence the band structure of the hybrid materials by the elemental composition in SnIP-related inorganic semiconductors of the general formula MXPn where M = Sn, Pb, X = Cl, Br, I, and Pn = P, As. This will allow beneficial band alignment in MXPn species for the specifically aimed application. Assessment of the properties and fabrication of the prototype devices will be performed within the project collaboration network.
