Outline of Final Research Achievements

As like the graphene which is composed of monolayer carbon atoms, various layered materials can be thinner as the atomic layer scale. I have studied the optical properties of "Layered materials" and discussed the mechanism of optical response. Obtained results are shown as forrowing,
Result 1. "We found that photoluminescence properties of layered materials can be controled by making the interface with molecular materials." Result 2. "We fabricated the solar cell made of layered materials, silicon, graphene, whose conversion efficiency becomes more than 11 %."Result 3. "The ineraction between excitons (photo generated electrons and holes)becomes enlarge in the layered materials."Result 4 "Photoluminescence due to the interaction between layers was observed in the hetero-structure of layered materials."
