| Super-Thin Crystals Promise Fast Memory Quote:
Thin crystalline sheets that shift the positions of their ions in response to an electric field look more promising as a fast, low power memory devices in personal and handheld computers, following new research in the US.
Work by Brian Stephenson and colleagues, at Argonne National Laboratory in Illinois, suggests there is no fundamental limit to the thickness of crystals that can exhibit this property, known as the ferro-electric effect. Previously scientists had found that films thinner than four nanometres ceased to exhibit ferro-electricity.
