Enhanced Photocurrent in Transparent Lead Zirconate-Titanate Thin Film Capacitors Under Sun Light Illumination

Ocola L.E., Li H., Auciello O., Argonne National Laboratory, US

A report will be presented on research focused on developing transparent Pb(ZrxTi1-xO3) (PZT)–based capacitor for photovoltaic device applications. The transparent PZT-based capacitors exhibit high photocurrents when exposed to Xenon (Xe) light that has wavelengths from [...]

Templated Self-Assembly of 5 nm Gold Nanoparticles

Ocola L.E., Lin X-M., Argonne National Laboratory, US

Combining top-down electron beam lithography and bottom-up colloidal chemical assembly can potentially lead to large scale patterning of nanocrystals on arbitary substates. Our approach consists of fabrication of templates from hydrogen silsesquioxane (HSQ) on treated [...]

Responsive Hydrogels as Model Materials to Study the Deformation Behavior of Patterned Polymer Nanostructures

Tirumala V.R., Stafford C.M., Huang R., Lin E.K., Ocola L.E., National Institute of Standards and Technology, US

The mechanical stability of polymer nanolines is crucial to the success of semiconductor device fabrication. Recent experimental and modeling studies have focused on the influence of processing conditions on the stability of densely patterned lines. [...]

Biologically Functionalized Nanochannels on Ferroelectric Lead Zirconium Titanate Surfaces

Ocola L.E., Pan W.C., Kuo M., Tirumala V.R., Reiss B.D., Firestone M.A., Auciello O., Argonne National Laboratory, US

We recently started a program at Argonne to exploit patterned, polarizable ferroelectric surfaces, such as lead zirconium titanate (PZT), as a means to create field-responsive inorganic-biomolecule interfaces to study and manipulate biomatter on surfaces. In [...]
