Background

Jung Ho Je works on “development and applications of X-ray imaging” based on using synchrotron hard X-rays. Phase contrast X-ray imaging with or without x-ray optics is his main concern of development. Specifically high spatial resolution of 10nm and high temporal resolution of <1ms are the main targets.

Prof. Je’s recent work has focused on the applications of X-ray imaging to dynamic studies of soft matters such as gas bubble/liquid systems, colloidal systems, living cell systems, etc. Unsolved fundamental phenomena in soft matters are investigated by visualizing in real-time internal structures in 2-dimension (2-D) or 3-D.

Another domain of research pursed by Prof. Je is in understanding the mechanism of defect formation during single crystal growth such as SiC, based on using phase contrast imaging combined with X-ray topography.

In addition he is working on fabrication of stretchable organic nanowire arrays. Specifically stretchable nano-devices for energy storage, photon-switch, gas sensor, photonic waveguide, etc. are investigated.
