Projects Synthesis Materials Fabrication Devices Characterization Theory
This year we have nearly 30 projects covering a wide range of nanoscience, including facile synthesis of organic and inorganic nanowires and nanostructures, novel fabrication routes, building of functional bioarchitectures, nanostructured devices and nanowire applications.

Hydrogen Gas Sensor based on Pd Nanopatterns by Electron beam lithography
In collaboration with Serhiy-cherevko and Prof. Chan-hwa Chung in the Chemical Engineering Department of SKKU, we are trying to explore the Hydrogen sensor applications of metallic nanostructures of Palladium. A thin organometallic film consisting of surfactant stabilized Pd-colloids will be directly patterned by electron-beam irradiation. Non-exposed colloids will easily removed by rinsing the sample with a typical developer. Its electrical characterization will be carried out to understand the metallic character of the nanostructures will be checked by resistance measurements. Pd patterned array structures are being investigated for the application of hydrogen sensing.
