Computers are getting smaller and smaller. And as hand-held devices – from mobile phones and cameras to music players and laptops – get more powerful, the race is on to develop memory formats that can satisfy the ever-growing demand for information storage on tiny formats.
Researchers at The University of Nottingham are now exploring ways of exploiting the unique properties of carbon nanotubes to create a cheap and compact memory cell that uses little power and writes information at high speeds.
Miniaturization of computer devices involves continual improvement and shrinking of their basic element, the transistor. This process could soon reach its fundamental limit. As transistors approach nanoscales their operation is disrupted by quantum phenomena, such as electrons tunnelling through the barriers between wires.
