New wave of technologies possible after ground-breaking analysis tool developed
Date:8/26/2012

A revolutionary tool created by scientists at the University of Sheffield has enabled researchers to analyse nanometer-sized devices without destroying them for the first time, opening the door to a new wave of technologies.

The nuclear magnetic resonance apparatus developed by the University's Department of Physics and Astronomy will allow for further developments and new applications for nanotechnology which is increasingly used in harvesting solar energy, computing, communication developments and also in the medical field.

Scientists can now analyse nanostructures at an unprecedented level of detail without destroying the materials in the process, a limitation researchers across the world faced before the Sheffield experts' breakthrough.

Dr Alexander Tartakovskii, who led a team of researchers, said: "We have developed a new important tool for microscopy analysis of nanostructures. The very tiny quantities of matter used in nanostructures the behavior of electrons and photons is governed by new quantum effects, quite different from what happens in bulk materials.

"Development requires careful structural analysis, in order to understand how the nanostructures are formed, and how we can build them to enhance and control their useful properties. Existing structural analysis methods, key for the research and development of new materials, are invasive: a nanostructure would be irreversibly destroyed in the process of the experiment, and, as a result, the important link between the structural and electronic or photonic properties would usually be lost. This limitation is now overcome by our new techniques, which rely on inherently non-invasive nuclear magnetic resonance (NMR) probing."

The results open a new way of nano-engineering, a full characterisation of a new material and new semiconductor nano-device without destroying them meaning more research and development and device fabrication processes.
