| Outline of Final Research Achievements |
For the purpose of exploiting new field of molecular biology based on quantum theory, it is necessary to devlelop an ultrathin window material, graphene, for time-resolved soft x-ray spectroscopy under ambient pressure. During the research, we fortunately exploited a research deployment on carrier dynamics, such as an observation that photoexcited carrier density is modulated, depending on the layer of graphene.

| Academic Significance and Societal Importance of the Research Achievements |
本研究では、僅かにグラフェンの積層が摂動を受けただけで、層毎にグラフェン中の光励起キャリアの密度が大きく変調されるという初めての研究成果が得られた。このことは、グラフェンの窓材としての量子生物学への応用だけでなく、光デバイス応用においても重要な研究成果になると考えられる。
