UW Madison: Carbon nanotubes could result into better transistors
In 1950s, transistors were launched commercially and since then they haven’t seen any replacement in technology or the way we have used them. For every day functioning, silicon and gallium arsenide transistors are being used. As per a University of Wisconsin-Madison research team, they have found a way to make a better transistor, which would be twice as good as the one being made of silicon.
The researchers have found the capability to develop even better transistors in carbon nanotubes. This material is said to be having rare properties, having carbon atoms linked in a cylindrical molecular structure.
Their structure makes them quite strong and provides them electrical semi-conductive properties. University of Wisconsin-Madison researchers have shared that the nanotubes have extraordinary properties, but its molecular scale makes it quite difficult to utilize the material’s potential completely.
Study’s co-researcher Michael Arnold was of the view, “There has been a lot of hype about carbon nanotubes that hasn’t been realized, and that has kind of soured many people’s outlook. But we think the hype is deserved”.
In the research paper published in the Science Advances, the University of Wisconsin-Madison team has mentioned that if they eliminate contaminated nanotubes, they will be come up with a transistor that has charge density 1.9 times higher than traditional silicon.
Arnold affirmed that it is a big achievement that carbon nanotube transistors are being made that are better than silicon transistors. This advancement was vital to try using carbon nanotubes in fields including logic, high-speed communications and semiconductor electronics technologies.
The advancement has raised a possibility that carbon nanotube transistors could replace traditional transistors one day. The researchers think that this advancement is vital for mobile technology as in it more current is needed to flow over a smaller area.
