Chemistry research
could produce faster computers
|
Chemists at the University of
Liverpool are helping to create future electronics
based on molecules for faster and smaller computers.
Experts have been working for many years to understand how to work with
electronic material produced on an increasingly small scale. In the emerging
field of nano-science and nano-technologies it is important for scientists
to be able to control the structure and bonding of molecules that are used
in creating small scale electronic components for products such as computers.
Scientists at Liverpool have succeeded in imaging and forming a unique
bond between a single gold atom and a single organic molecule called a
pentacene. They managed to bind the atom to the pentacene and take images
of rearrangements of the electrons participating in the formation of the
chemical bond.
The team selected the pentacene as it is a special class of molecule that
has qualities of particular use in molecular electronics. The gold atom
is a metal atom that attracts an extra electron.
Professor Mats Persson, from the University's Department of Chemistry said: “This
new experiment allows us to control the arrangement and shape of chemical
bonds and to gain new insight into making contact with a single molecule
with potential importance for molecular electronics. There will come a
time when electronic material will become so small that we will need to
control the structure down to the atomic scale and the chemical bonds between
single molecules and atoms.
“The atomic scale control of single-molecule chemistry in this experiment opens
up new perspectives in the emerging field of molecular electronics, particularly
in connecting organic molecules with electronic components. This could be important
in creating electronics for future computers which are faster, smaller and have
less power consumption.”
The research, conducted in collaboration with IBM Zurich Research Laboratory,
Switzerland; Tampere University of Technology (TUT), Finland; and Chalmers
University of Technology (CTH), Sweden, is published in Science magazine. |

1. The University of Liverpool
is one of the UK's leading research institutions.
It attracts collaborative and contract research
commissions from a wide range of national and
international organisations valued at more than £90
million annually.
