Platinum to boost computer memory

A new transistor has been created using platinum which could dramatically increase the speed of computer memory.

It has been reported that scientists from the University of California-Los Angeles have taken a 30-nanometre-long piece of tobacco mosaic virus and coated it in platinum to develop super-fast memory chips.

The nanoparticles could be used in computers and other devices, such as MP3 players, to radically improve their speed and memory size.

The transistors built from the nanoparticles have been sandwiched between two electrodes and are apparently easy to switch between ‘on’ and ‘off’ states because they do not need to build up a charge at a capacitor before they can be switched.

This breakthrough, reported in the Nature Nanotechnology journal, comes following the recent discovery that nanoparticles used in fibre optic cables could be utilised to transform the cables into detectors of certain chemicals. Link to Source
