Each nanonet transistor consists of numerous strips of nanotubes, separated bylines that are etched in place. The lines are easy to create with a standard etching process used in the semiconductor industry.
Future research may include work focusing on learning the reliability of the carbon nanotube circuits.
The research has been funded by the National Science Foundation through the Network for Computational Nanotechnology at the Birck Nanotechnology Center in Purdue's Discovery Park. The Illinois portion of the research also was funded and supported by the NSF, U.S. Department of Energy, Motorola Corp., and by the university's Frederick Seitz Materials Research Lab, the Center for Microanalysis of Materials and the Department of Chemistry.
The researchers used computers made available by a global network called the nanoHUB, an Internet-based science gateway that provides computer-based resources for research and education in the areas of nanoelectronics and nanoelectromechanical systems and their application to nano-biosystems.
"This work requires tremendous computing resources because these are not trivial calculations," Alam said.
Nanoelectronics focuses on creating a class of electronic devices containing features measured in nanometers, equivalent to one-billionth of a meter. A nanometer is about the size of 10 atoms strung together.
The Network for Computational Nanotechnology uses advanced theory and simulations to explore new ideas for digital switching devices such as innovative types of transistors that promise to help researchers create future electronics.
