Data on Electroceramics Described by Researchers at Pusan National University (Multifunctional Ru-AlN heating resistor films for high efficiency inkjet printhead)
By a News Reporter-Staff News Editor at Journal of Technology -- Data detailed on Electroceramics have been presented. According to news reporting originating in Pusan, South Korea, by VerticalNews journalists, research stated, "Ru-AlN thin films were suggested as a novel multifunctional heating resistor film for non-passivated type thermal inkjet printer devices. Ru-AlN thin films were prepared by plasma-enhanced atomic layer deposition in order to intermix Ru and AlN precisely."
The news reporters obtained a quote from the research from Pusan National University, "When the Ru intermixing ratios were optimized, Ru-AlN films showed a favorable electrical resistivity (from 490.9 to 75.3 mu Omega cm) and minimized temperature coefficient of resistance (TCR) values (from 335 to 360 ppm/K). Moreover, the Ru-AlN films showed a strong oxidation resistant as compared with commercially used TaN0.8 films because the prepared Ru-AlN thin films had a typical nanocomposite structure."
According to the news reporters, the research concluded: "By applying electrical pulses to the heater device using Ru-AlN thin films for a Joule heating, a reliable operation was also proven."
