Latest Patents

One of Windisch’s listed patents, “Magnetic Transparent Conducting Oxide Film and Method of Making,” describes cobalt-nickel oxide films produced by spin-casting aqueous or organic precursor solutions and annealing them in air at 450°C. The films are approximately 100 nanometers thick, and reported resistivity can be as low as 0.06 Ω·cm. Films deposited on sapphire are described as relatively transparent across wavelengths from 0.6 to 10.0 micrometers, with a refractive index of about 1.7, and as magnetic.

The patent description examines how composition affects the films’ properties. It reports that small additions of lithium can lower resistivity, while substituting elements such as zinc or aluminum for nickel can increase resistivity but improve some mechanical properties. X-ray diffraction, X-ray photoelectron spectroscopy, ultraviolet-visible spectroscopy, and Raman spectroscopy were used to study the materials. The findings identify a nickel-cobalt oxide composition as the primary conducting component and describe how deviations in the cobalt-to-nickel ratio can reduce conductivity.
