| Outline of Research at the Start |
1) Obtaining the fabrication conditions of multilayer (in the SVE method) in organic-inorganic hybrid perovskite - SVE method and basic characterizations with SEM, XRD, XPS ,etc.
2) Understanding the phonon vibration modes of the formed multilayers using THz-TDS - Flexible substrate and polymer protection layer - Intrinsic and interfacial phonon vibration modes
3) Optimizing the real conductivity (< 50 S/cm) and board THz absorption (0.5-3 THz) in multilayers - Try to create a new type THz-detector

| Outline of Annual Research Achievements |
The research goal in R5: Various bilayer fabrications and obtaining their conditions.
1) To fabricate a well-defined multilayer, we have performed several test experiment using the bilayer. Before this, we have finished the investigation of phonon vibration of all-inorganic perovskite such as CsPbI3.
2) We found the annealing conditions to completely separate two layers in hybrid perovskite was not easy in ex-situ environment.
3) Currently, we are considering to make an in-situ annealing system in our vacuum chamber.
4) Also, we have summarized our related research results and published one review paper at Small Sciences (IF = 12.7)

Current Status of Research Progress
3: Progress in research has been slightly delayed.
Reason
We have finished obtaining the method of bilayer fabrication now. However, we want to find more complete conditions for triple-layer and more. Currently, we are considering an in-situ annealing system in our vacuum chamber.
|
| Strategy for Future Research Activity |
For R6,
1) We will construct an in-situ annealing system in our vacuum chamber.
2) We will perform the investigation of phonon vibration mode in bilayer and triple-layer.
3) We will focus on the original and interfacial phonon modes with their physical origins.
4) If possible, we will perform high-resolution measurement using synchrotron radiation techniques such as XPS, NEXAFS, and EXAFS.
