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. Please browse the menu (hover on a group and click on the project of choice) to view brief overviews of our projects.
Density Control of ZnO Nanowires
In collaboration with Prof. H. S. Shin (UNIST), Dr. J. I. Sohn (University of Cambridge), Prof. W. T. S. Huck (University of Cambridge), Prof. M. E. Welland (University of Cambridge), and Prof. H. C. Choi (POSTECH), we work on the study of the density control and the uniform distribution of ZnO nanowires (NWs). Au nanoparticles (NPs) have been used as a catalyst to control the density of ZnO NWs. We have taken several approaches to control the density of ZnO NWs on patterned surfaces with uniform diameter using Au NPs as a catalyst.
