A multi-scale modeling study at Penn reveals a new theory of behavior for domain-wall motion in ferroelectric materials, reproducing experimental data long at odds with existing theories. The study confirms that small dipoles play a key role in smoothing transition regions as the wall moves.
Dr William O'Brien Jr is recognized for his numerous contributions to the scientific progress of diagnostic medical ultrasound. He has published 318 papers and received a National Institutes of Health MERIT award.
A team of researchers, led by Lehigh University's Volkmar Dierolf, has received a $1.2-million grant to study the nanostructure of ferroelectric domains. They aim to image and control these domains at the nanoscale to engineer devices.
Scientists have discovered a new method to stabilize ferroelectricity in nanostructures using fragments of water, leading to ultra-dense memory storage devices with unprecedented capacities. This breakthrough could enable the creation of storage devices small enough to hold massive amounts of data, such as music or video libraries.
A new EU project is focused on developing cheaper, smaller ferroelectric films for use in microwave communication devices. These films have high dielectric permittivity and can be used to create voltage-controlled capacitors and tuneable microwave components.
Dr. Chen will use his Guggenheim Fellowship to research the structures and properties of ferroelectric and multiferroic thin films with potential applications in various functional devices. He aims to develop theories and multiscale computational models for predicting their behaviors.
Engineers have used X-rays to study how atoms rearrange themselves in ferroelectric materials as they switch between electrical pulses. As the material fatigues, progressively larger areas cease working, suggesting that the atoms' switching ability decreases over time.
