| 研究開始時の研究の概要 |
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

| 研究実績の概要 |
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)

3: やや遅れている
理由
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.

| 今後の研究の推進方策 |
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.
