Researchers at RMIT University have engineered a new type of transistor, the building block for all electronics. Instead of sending electrical currents through silicon, these transistors send electrons through narrow air gaps, where they can travel unimpeded as if in space.
The device unveiled in material sciences journal Nano Letters, eliminates the use of any semiconductor at all, making it faster and less prone to heating up.
Lead author and Ph.D. candidate in RMIT's Functional Materials and Microsystems Research Group,Ms Shruti Nirantar, said this promising proof-of-concept design for nanochips as a combination of metal and air gaps could revolutionise electronics.
"Every computer and phone has millions to billions of electronic transistors made from silicon, but this technology is reaching its physical limits where the silicon atoms get in the way of the current flow, limiting speed and causing heat," Nirantar said.
"Our air channel transistor technology has the current flowing through air, so there are no collisions to slow it down and no resistance in the material to produce heat."To read more, click here.
