概要(目的・用途・実施内容)/ Abstract (Aim, Use Applications and Contents)
1. Investigating the hyperbolic plasmon properties of a new layered material: MoOCl2, which has potential application in nonophotonics and polarization devices.2. Investigating Au plasmon-TiO2 metasurface strong coupling for near-field enhancement.
実験 / Experimental
1. Using the microfigure measuring instrument to measure the thickness of layered material. Then, measuring the transmission spectra of the material with different thickness with FTIR.2. Using Sputtering to deposite 100nm Au on ITO glass, and then using ALD to grow TiO2 film, and making strucutres with EB Lithography and further Au sputtering. Finally getting Au nanostrucutrures on TiO2/Au film. Using the Scanning Probe Microscopy to obseve the quality of nanostructures.The sample preparation was done using the ARIM facility, while the FTIR and SPM characterization were done elsewhere.
結果と考察 / Results and Discussion
1.I measured the thickness of several MoOCl2 thin films with the microfigure measuring instrument, with thicknesses in the range of ~10-1000 nm. I found that the MoOCl2 thin film has good polarization properties.2. I fabricated Au/TiO2 film structures, further optimizing is still in process.
