Superconducting circuits find applications in sensing and information processing. Credit: Lancaster University Lancaster scientists have demonstrated that other physicists’ recent “discovery” of the field effect in superconductors is nothing but hot electrons after all. A team of scientists in the Lancaster Physics Department have found new and compelling evidence that […]

Credit: Pixabay/CC0 Public Domain Nature’s strongest material now has some stiff competition. For the first time, researchers have hard evidence that human-made hexagonal diamonds are stiffer than the common cubic diamonds found in nature and often used in jewelry. Named for their six-sided crystal structure, hexagonal diamonds have been found at […]

Purdue researchers have figured out a way to calculate surface viscosity just by looking at a stretched droplet as it starts to break.

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: […]
