Research summary
Fabrication and Application of Advanced Heterostructure Materials Utilizing powder metallurgy technology, we are developing innovative materials by controlling various heterostructures. We control the microstructure in a unique network and develop materials with excellent mechanical and physical properties. Since such excellent properties depend on the unique microstructure, we perform various analyzes using an electron microscope.
