“Computer chips are constantly getting smaller and smaller. There’s an unrelenting decrease in size. And the question arises, how do you wire these things in"” said Dr. Jillian Buriak, University of Alberta professor and senior research officer at the National Institute for Nanotechnology. “If you’re going to make something on the order of 22 or even 18 nanometres, then you’d better have a plug that’s about that size, too.”
A team of NINT researchers, headed by Buriak, has demonstrated an innovative technique for producing very small conductive nano-wires on silicon chips. The process can produce nano-wires that are 5,000 times longer than they are wide. The innovative technique for producing very small conductive nano-wires on silicon chips meets the need for connecting ever-smaller transistors and other electronic components.
“You need very tiny wires to connect everything,” said Buriak. “We’ve figured out a way to use molecules that will self-assemble to form the lines that can be used as wires. Then we use those molecules as templates and fill them up with metal, and then we have the wires that we want. You use the molecules to do the hard work for you.”
In one example, 25 parallel platinum nano-wires were made using this self assembly process, with each wire measuring only 10 nm in width, but extending to a length of 50 microns.
While the idea of wires ‘self-assembling’ sounds like something from science-fiction, it’s a natural process, says Buriak.
“You are the product of self-assembly. The way DNA forms a double helix is self-assembly. It’s just that molecules will recognize each other, bind to each other and then they’ll form structures,” she said. “And the molecules we’re using are actually very simple. They’re just polymers, just plastics that do that naturally.”
While the new process could provide the solution for computer manufacturers looking for ways of increasing the speed and storage capacity of electronics, it could also mean cheaper electronics as well.
“If you have to go and lithographically define one single wire, it’s going to be painstakingly hard and expensive,” said Buriak. “But, if you can have a cheap molecule do it for you, that’s great, that’s going to be much cheaper, use much less energy and be a little more environmentally friendly.”

In just a few weeks from now, the Chinese space station Tiangong-1 will re-enter the Earth's atmosphere where it will to a large extent burn up. It is possible that some debris will reach the Earth's surface. Tiangong-1 is orbiting the Earth uncontrolled at a speed of approx. 29,000 km/h.Currently the prognosis relating to the time of impact currently lies within a window of several days. The scientists at Fraunhofer FHR have already been monitoring Tiangong-1 for a number of weeks with their TIRA system, one of the most powerful space observation radars in the world, with a view to supporting the German Space Situational Awareness Center and the ESA with their re-entry forecasts.
Following the loss of radio contact with Tiangong-1 in 2016 and due to the low orbital height, it is now inevitable that the Chinese space station will...
