At the interface between silicon dioxide and silicon carbide, irregular clusters of carbon rings occur, which disturb the electronic function. Credit: Universität Basel, Departement Physik/Swiss Nanoscience Institute In power electronics, semiconductors are based on the element silicon—but the energy efficiency of silicon carbide would be much higher. Physicists of the […]

LEDs made of indium gallium nitride provide better luminescence efficiency than many of the other materials used to create blue and green LEDs, but a big challenge of working with InGaN is its known dislocation density defects that make it difficult to understand its emission properties. Researchers report an InGaN […]

Doped charges in the CuO2 planes of cuprate superconductors form regular one-dimensional ‘stripes’ at low temperatures. Excitation with ultrafast near-infrared pulses allows direct observation of diffusive charge dynamics, which may be involved in the establishing in-plane superconductivity.

This greatly magnified image shows four layers of atomically thin materials that form a heat-shield just two to three nanometers thick, or roughly 50,000 times thinner than a sheet of paper.

Three of the images collected at Argonne National Laboratory’s Dynamic Compression Sector, highlighting diffracted signals recorded on the X-ray detector. Section 1 shows the starting face-centered cubic structure; Section 2 shows the new body-centered cubic structure at 220 GPa; and Section 3 shows the liquid gold at 330 GPa. Credit: […]

Electrified water droplets take on a variety of distorted shapes just before bursting, based on the strength of the electric field. The profiles of different distorted droplet shapes are shown, overlaid on an image of one particular distorted droplet for comparison.
