研究テーマ
Research Subject

High energy resolution EELS to get IR (infra-red) spectra from various polymers in order to realize the high resolution chemical maps of different polymer compounds.

研究の背景 Background

Using Electron Microscope for understanding the structure and dynamics of nanomaterials on an atomic scale.

研究の目標 Outcome

Using Electron Microscope for –
a. Momentum and position resolved mapping of Transmission Electron Energy Loss Microscopy
b. Measuring the molecular vibrational states at different interfaces by high-resolution monochromatic STEM
