RMIT University researchers have engineered a new type of transistor that send electrons through narrow air gaps where they can travel unimpeded, rather than sending electrical currents through silicon.
“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,” lead author and PhD candidate in RMIT’s Functional Materials and Microsystems Research Group Shruti Nirantar said in a statement.
“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.”
While the power of computer chips has doubled about every two years for decades, recently the progress has stalled as engineers struggle to make smaller transistor parts.
However, the researchers believe the new device is a promising way to create nano electronics that respond to the limitations of silicon-based electronics. more>
