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
2】Experiment
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
3】3D
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.
