This portfolio includes carbon nanotube growth and processing methods relevant to nanotube manufacturing. Patterned Catalyst Techniques for Aligned Single-walled Carbon Nanotube GrowthSingle-walled carbon nanotubes (SWNTs) feature exceptional electric properties (conductivity and semi-conductivity) that make them attractive for nano-electronics, optics, material applications and more. This SWNT growth technology yields a dense structure without degraded alignment by eliminating undesired interactions between the SWNT and catalysts on the growth surface. More specifically, a patterned catalyst is used to provide a template to direct SWNT growth, resulting in perfectly aligned high coverage SWNTS. Benefits
Applications
Medium Scale Carbon Nanotube Thin Film Integrated Circuits on Flexible Plastic SubstratesThis technology improves the performance and consistency of integrated circuits featuring semi-conductive carbon nanotube (CNT) transistors. Specifically, metallic conductive pathways in random nanotube networks are reduced using a medium scale carbon nanotube thin film. This process reduces these pathways by cutting fine lines into the carbon nanotube network while preserving its semiconducting properties. Benefits
Applications
Using Nanoscale Thermocapillary Flows to Create Arrays of Purely Semiconducting Single-Walled Carbon NanotubesThis carbon nanotube (CNT) purification technology facilitates scalable, damage-free separation of arrayed metallic and semi-conductive CNTs. Resulting CNT arrays may be large and feature high Ion/Ioff ratios, allowing for less power loss while powered off, faster switching times, and overall lower operating voltage. The invention improves CNT array quality by creating a temperature gradient to release metallic CNTs from the array matrix. Benefits

Dr. Nenad Miljkovic’s research group has developed a new technology to reduce the susceptibility of metallic surfaces to fouling/scaling. The invention is a thin (<~100 nm) multi-layered solid-state coating that reduces the surface energy and nucleation site density of metals such as aluminum, copper, and more. The technology has been demonstrated to reduce scale accumulation by 95% as compared to uncoated surfaces and eliminates the intrinsic durability issues of oil-based coatings. Applications for the technology include the reduction of scale build-up on air conditioning and refrigeration systems and the prevention of coke deposition for aviation applications. |
