For the last
decade, engineers and scientists have tried to use the unique properties of carbon nanotubes to create high-performance electronics devices
that are faster or energetically more efficient. That means longer battery life and higher speed of
electronic devices such as
laptops, smartphones.
Until now,
silicon and gallium arsenide used in computer
chips and personal electronics. Engineers from University of
Wisconsin-Madison material science achieved current that's 1.9 times higher than silicon transistors.
Michael Arnold who is head of this research team, said that
"This achievement has been a dream of nanotechnology for the last 20
years,". Also he claimed that carbon nanotube transistors that are better than silicon transistors is a
big milestone.
As to extrapolations from single nanotube measurements, carbon
nanotube transistors should be able to perform five times faster or use five times less energy than silicon
transistors. Thanks to carbon nanotube's ultra-small dimension, it is
possible to rapidly change a current signal traveling across it. This process
is very important for wireless communications devices.
