Successful imaging of individual atoms and associated electric fields in ferroelectrics could lead the way to a new era of advanced electronics As scientists learn to manipulate little-understood nanoscale materials, they are laying the foundation for a future of more compact, efficient, and innovative devices. In research to be published online July 8 in the journal Nature Materials, scientists at the U.S. Department of Energy's Brookhaven National Laboratory, Lawrence Berkeley National...

Engineering researchers at the University of Michigan have found a way to improve the performance of ferroelectric materials, which have the potential to make memory devices with more storage capacity than magnetic hard drives and faster write speed and longer lifetimes than flash memory. In ferroelectric memory the direction of molecules' electrical polarization serves as a 0 or a 1 bit. An electric field is used to flip the polarization, which is how data is stored. With his colleagues at...

Scientists at Tohoku University in Japan have recorded data at a density of 4 trillion bits per square inch, which is a world record for the experimental "ferroelectric" data storage method. As described the journal Applied Physics Letters, which is published by the American Institute of Physics, this density is about eight times the density of today's most advanced magnetic hard-disk drives. The data-recording device scans a tiny cantilever tip that rides in contact with the surface of a...

U.S. government scientists say they have created a method of measuring the intrinsic conducting properties of ferroelectric materials. The researchers at the Center for Nanophase Materials Sciences at the U.S. Department of Energy's Oak Ridge National Laboratory in Tennessee say their achievement could lead to much smaller, faster and more powerful electronic devices. For years, the challenge has been to develop a nanoscale material that can act as a switch to store binary information, Peter...
