| Outline of Final Research Achievements |
In this research, low work function surfaces were created and investigated for applications in photon-enhanced thermal energy converters. Since the efficiency of such device largely depended on a work function of a collector, formation of a carbon surfaces was extensively studied for its low work function and thermal stability.
Formation of a uniform polycrystalline diamond surface by using nano-diamond precursors was established. As for the evaluation of work functions, Cs coated surface of GaAs as well as n-type single crystal diamond were investigated, which resulted in discovery of key schemes for enhancing a performance of energy converters.
