08 Nano-structure Imaging

Developing the method of Diffractive Imaging for 3D atomic resolution of nanostructure materials.


[Target 1] Sophistication and application of Diffractive Imaging

Low-damage imaging of an electron microscope with high resolution and high contrast is required for radiation-sensitive materials, for example, biological samples or carbon materials. We will develop an experimental method of low-voltage imaging that can be applying for nanomaterials composed of light atoms, which are generally damaged by electron beam.


Target 2Experiment of 3D atomic resolved imaging

We will conduct experiments of 3D atomic resolved imaging of carbon nanotube and graphene using the method developed in Target 1.


Target 33D atomic resolved imaging of biological molecules

3D atomic resolved imaging of nanomaterials on graphene will be conducted. Target materials are atoms, molecules, molecular complexes, etc. Furthermore, imaging of biomaterials containing water molecules will be challenged.
