Latest Patents

Parthangal holds a patent titled "Approach to contacting nanowire arrays using nanoparticles." This invention provides an in situ method for connecting and electrically contacting vertically aligned nanowire arrays using conductive nanoparticles. The utility of this approach is demonstrated through the development of a gas sensing device that employs the nanowire assembly. The process involves growing well-aligned, single-crystalline zinc oxide nanowires through a direct thermal evaporation process at 550°C on gold catalyst layers. Electrical contact to the top of the nanowire array is established by creating a contiguous nanoparticle film through the electrostatic attachment of conductive gold nanoparticles exclusively onto the tips of the nanowires. The resulting gas sensing device is sensitive to both reducing (methanol) and oxidizing (nitrous oxides) gases. This assembly approach is versatile and can be applied to any nanowire array requiring a top contact electrode.
