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.
Electrical Properties of Transparent Metallic Indium Doped Zinc Oxide Nanoelectrodes
In this project the spin-coatable IZO resist will be prepared by chemically reacting indium nitrate with zinc naphthenate in toluene. The resist will be exposed with an electron beam sensitivity of 6.15 mCcm-2 and contrast (γ) 2.27. Electron beam direct write technique will be used to pattern ZnO and IZO nanolines on pre-patterned Si/SiO2 substrate. The patterned structures will be annealed at 6500C in Ar + 5% H2 for 2 hour. Electronic transport in IZO and ZnO nanolines will be studied by four probes on lines ranging from 90 nm to 320 nm in width and over a range of indium molar percentage concentrations.
