Outline of Final Research Achievements

In this project I aimed to develop a novel method with high spatial resolution and high time-resolution utilizing photo-thermal conversion phenomena. The major achievement of my project during the period is the following three topics: 1) We found a huge optical response from graphene monolayer on Ir(111) which is intercalated by alkali atoms. We revealed the origin of the peculiar feature as a graphene plasmon which is activated by moire superstructure inherent in the　system;　(2)　We　have　developed　two-dimensional　electronic　spectroscopic　system　with　photo-thermal　conversion; (3) We have investigated assembly structural dependence of the excited state relaxation dynamics of tetraphenyldibenzoperiflanthene thin films.
