The purpose of this research is to develop the materials interface technology, which is based on the control of the interface structure, for material processing and to apply it to the fabrication of some technologically important materials. In the course of the research, structural transition and chemistry variation at the interface will be quantitatively measured and simulation of interface structure will also be carried out. In particular, generalization of the principles of microstructural evolution, which were suggested by our group, will be attempted by demonstrating that the principles are applicable to different metallic as well as ceramic materials. The principles will also be applied to the production of commercial ceramic materials and components.

Fabrication of polymer piezoelectric materials with high power density using nano structure.

Our team has been developed ① fabrication of P(VDF-TrFE) films and sheets using tape casting and solution deposition techniques and ④ aligned nano rod structure. P(VDF-TrFE) films and sheets being under developed have better piezoelectric properties and higher power density compared to commercially available PVDF sheets. The processing of the tape casting and solution deposition techniques will be improved and established, and optimum films and sheets will be fabricated. In order to increase the effective area of power generation, ② multi layer stacking and ③ spiral structures will be developed using the films and sheets. Optimum process conditions will be established using the study of various processing variables. Stacking and spiral structures are expected to provide higher power density than the single layer of the film and sheet, but the effective area of the power generation will further increased using ④ aligned nano rod structure and ⑤ composite structure of metal nano particle and polymer piezoelectric. The processing of the aligned nano rod structure will be improved and established, and optimum aligned nano rod structure will be fabricated. A new concept of processing is required for the composite structure of metal nano particle and polymer piezoelectric. The micro and nano structures and physical and chemical properties will be investigated. The multi stacking and spiral structures of the nano structures will be fabricated. The electrical properties of nano level structures will be investigated using SPM (Scanning Probe Microscopes).

Our research goal of FAND group is to develop the flexible electronic systems using high performance nanomaterials and soft electronic technologies. This flexible technology could provide interesting opportunities for printable electronics such as flexible displays, artificial skins, biosensors, roll-up communication, and biomedical applications for human body integration. Our laboratory is also involved in the development of flexible energy systems such as self-powered nanogenerator and batteries for not only operating the mobile consumer electronics but also convirting the tiny movements of human into electricity. Our studies are also interested in developing new flexible nanomaterials using laser material interaction such as excimer or solid state laser in the application fields of 3D IC, nanomaterial research, localized high temperature crystallization and thermal annealing that are compatible with flexible substrates.

Another research aim of our group is to develop the semiconductor nano-transisotors utilizing advanced VLSI (very large scale integration) technology Innovative device structures, new materials and process are investigated to overcome the limitation of current MOSFETs. Finally, integrating state-of-art nanodevice technologies into flexible electronics allows to open new fusion applications in the field of IT, health, and nano-bio technologies.

The basic concept of this research is that design of bimetallic nanoparticles and synthesis of conductive nano-ink for manufacturing low cost, low temperature, fast, simple and eco-friendly printed electronics. To reduce the trial and error, we adopt simulation for expecting on nano phase diagram by thermodynamic relations, in advance. With this process, we will introduce new method for synthesizing bimetallic nano particles in many applications. To apply in electronic devices, reliability test and comparison should be performed also.
The research will proceed in two steps; 1) development of bimetallic nano structure and synthesis Ag-Cu, Ag-Al nanoparticles based on drawing results, in this stage, we use simulation such as MD, MC, DFT for mapping out nanophase diagram 2) test plastic substrates with produced nano-ink and paste in 1st step. In addition, manufacture printed electronic device on transparent plastic substrate followed by conductivity, adhesion, performance and reliability test.
