| Outline of Final Research Achievements |
In the current study, it was clarified that spectrally-controlled enhancement of near-field radiation transfer through a hundred nanometer-scaled vacuum gap was achieved using a nanometer-sized pillar-array structured surface by a factor of about 100 compared with propagating (far-field) radiation transfer by blackbody surfaces through a numerical simulation. In addition, a spectrally-controlled absorption thermophotovoltaic cell made of a thin semiconductor layer sandwiched by a fishnet-type electrode and substrate electrode was manufactured successfully and would be applied for a photovoltaic generation of electricity by combining with the above emitter.
