01 Inorganic Materials

In this project, we elucidate three dimensional atomic structure of “3D active-site”, which is source of various functionalities. We create 3D active-site materials that have high performance functionalities, by fabricating advanced semiconductors and functional materials and analyzing their structures with holographic technologies.

 

[TARGET1] Creation of dopant active-sites and elucidation of their structures

We elucidate three dimensional atomic structure around dopants and defects in advanced semiconductors and functional materials by using doped atom holography and first-principle calculation in order to investigate the origin of functionalities.

 

[TARGET 2] Creation of surface/interface active-sites and elucidation of their structure and electronic states

We elucidate atomic structure and electronic states of surface/interface nanostructure in advanced semiconductors and functional materials by using surface/interface holography, nanostructure imaging, and first-principle calculation.

 

[TARGET 3] Device applications of 3D active-site materials and creation of novel functionalities by merging different materials

We exploit obtained “3D active-site” atomic structure to realize high performance functionalities in semiconductor devices. In addition, we create novel functionalities by merging different materials such as organic functional material.
