Using a new technique, Paul Malinowski and other researchers in Kyle Shen’s lab found that iron selenide’s superconducting “dome” is more closely linked to resistance caused by imperfections in its crystal lattice than to the number of electrons flowing through the crystal. @Chris Kitchen/College of Arts and Sciences Cornell physicists have discovered that minimizing disorder, not varying electron count, is the key factor for controlling the superconductivity in the unique ma

Scientists have shown that a material treated for 40 years as a uniform, textbook superconductor is in fact a patchwork of different crystal structures throughout its bulk, using one of the latest 3D imaging techniques to see deep inside the crystal for the first time. High-temperature superconductivity is widely regarded as one of the most significant scientific discoveries of the past 40 years. It promises technologies built on electricity that flows with zero resistance an

Drops of various liquids and in different states of matter were allowed to slide across surfaces. The researchers were thus able to determine that even more factors play a role in the phenomenon known as “slide electrification” than previously thought. Whether on a windowpane at home or during the industrial cleaning of computer chips: Droplets sliding over solid surfaces become electrically charged. Yet the physical mechanism behind this charging remains a subject of debate

Put a drop of water into a very hot pan and it can skitter across the surface on a cushion of vapor. This is known as the Leidenfrost effect. Now, scientists have observed a related phenomenon involving ice and an extremely hot surface – on a length scale of nanometers and within nanoseconds. The effect was discovered and investigated by an international team of researchers at the FXE instrument at European XFEL and could influence, for instance, laser processing, data storag

A graphic showing the screening of magic-angle superconductivity Scientists from the National Graphene Institute at The University of Manchester have demonstrated that superconductivity in magic-angle graphene can be completely switched off by screening interactions between electrons. The finding provides strong evidence that electron interactions play a central role in the phenomenon and helps address a key question that has remained unresolved since superconductivity was fi

Breakthrough from a team led by Jacob Covey, associate professor in the University of Chicago’s Pritzker School of Molecular Engineering and Department of Physics, turns helium-3’s low mass into a quantum resource
