[资源] Researchers Fabricate Complex SWNT Architectures

如何将碳纳米管应用以及和芯片集成的确是一个不错的方向哦～～～，不知道有没有虫子做这方面的研究呢：）
Researchers Fabricate Complex SWNT Architectures Using Newly Developed Assembly Process

Given the sheer number of potential applications for carbon nanotubes, experts in the field of nanotechnology are developing effective ways to mass produce intricate nanoscale structures for electronics, sensing, energy and biomedical applications in a timely, cost-effective manner with a high level of accuracy.

Using a new assembly process, a team of researchers at Northeastern University’s National Science Foundation (NSF) Nanoscale Science and Engineering Center for High-rate Nanomanufacturing (CHN) manufactured large-scale patterned single walled carbon nanotube (SWNT) networks in complex patterns. Led by Ahmed Busnaina, Ph.D., the William Lincoln Smith professor and director of Northeastern’s CHN, and professor Yung-Joon Jung, the researchers built intricate SWNT architectures with a high degree of accuracy, laying the foundation for the nanomanufacturing industry to overcome a major obstacle – precise and accurate placement of SWNTs.

These findings were published online in the Journal of the American Chemical Society. The research was funded by the National Science Foundation.

The researchers used a nanotemplate guided fluidic assembly process for optimum accuracy and control over the placement of the SWNTs on a silicon wafer. Using this fluidic assembly process for the SWNTs assembly enabled a highly controlled environment at the nanoscale. A surface treatment on the substrate, or wafer, made SWNTs highly attracted to the surface. As a result, the team was able to build highly organized SWNT architectures in various dimensions and geometries.

This assembly method can be extended to scales as small as a few nanometers while the length of the architecture is scalable up to 12” wafers.

“This novel process helps us better understand the fundamental mechanism governing the assembly of SWNTs and it finally makes building large-scale (wafer-level) nanoscale structures and networks of single-walled nanotubes possible,” said Busnaina.

The potential applications of these complex structures include transistors, horizontal interconnect systems, complex SWNT-based materials and various types of sensors, batteries, photovoltices, medical and biotechnology applications.
