In addition to chalcogenide-type semiconductor nanoparticles, considerable recent focus of nanocomposite research has turned to solar energy and thus to fullerene-based stmctures (i.e., C-60 and its derivatives) as electron acceptors. While fullerenes are smaller than typical nanoparticulate materials ( lnm diameter), many issues associated with dispersion and phase separation are shared between C-60 and other nano-partides. C-60 itself has excellent electronic properties including a high electron affinity, very high electron mobility, and the ability to be reversibly reduced with up to six electrons unfortunately, C-60 has limited solubility and hence is not solution processable. Therefore, C-60 functionalization is almost always used to impart processability and dictate miscibility, yet preserve the desired electronic properties, much in the same way the ligands are chosen to tailor QDs.

As with the n-TiCte and n-SrTiCh counterparts discussed earlier in Section 6.2 of this Chapter (see also Ref. 407), luminescence probes have proven to be very useful for unraveling the mechanistic details of the cathodic processes both at n-type (e.g., n-GaAs)556 and p type (e.g., p InP)557,558 Group III V semiconductor surfaces. Finally, these semiconductors share another trend with those discussed earlier (metal chalcogenides) in that the majority of the studies since 1990 have been directed at solid solutions (alloys of GaP and InP, GaAs and InAs etc.). These newer studies will be addressed in Section 12 of this Chapter.
