The Spintronics Technology Revolution Could Be Just a Hopfion Away

Artist’s drawing of characteristic 3D spin texture of a magnetic hopfion. Top layer shows a simulation of the spin structure viewed with surface-sensitive X-PEEM; bottom layer is a simulation of a bulk-sensitive X-ray transmission microscopy image; middle layer – colors indicate the varying direction of the spins showing the winding characteristic.

An Innovative Pattern: Scientists Rewrite Rules for 2D Electronics

2D Electronics Get an Atomic Tuneup

Electron microscopy experiments revealed meandering stripes formed by metal atoms of rhenium and niobium in the lattice structure of a 2D transition metal dichalcogenide alloy. (Image courtesy of Amin Azizi)

Toward an Ultrahigh Energy Density Capacitor

To make the new material, the thin film is first deposited via a pulsed-laser deposition process in this chamber. The bright “plume” you see is the laser hitting the target and depositing the material.

The Best Topological Conductor Yet: Spiraling Crystal Is the Key to Exotic Discovery

Image - This illustration shows a repeated 2D patterning of a property related to electrical conductivity, known as the surface Fermi arc, in rhodium-silicon crystal samples. (Credit: Princeton University/Berkeley Lab)

Scientists Take a Deep Dive Into the Imperfect World of 2D Materials

Image - This image, taken at Berkeley Lab's Molecular Foundry, shows an illustration of the atomic structure of a 2D material called tungsten disulfide. Tungsten atoms are shown in blue and sulfur atoms are shown in yellow. The background shows groupings of flakes of the material (dark gray) grown by a process called chemical vapor deposition on a titanium dioxide layer (light gray).

Scientists Discover ‘Chiral Phonons’ – Atomic Rotations in a 2-D Semiconductor Crystal

Animation - The atomic motion in a 2-D material, tungsten disulfide, is shown in this animation. In this phonon mode (known as longitudinal or LO), the selenium atoms (yellow) rotate clockwise while the tungsten atoms (blue) are still. (Credit: Hanyu Zhu, et al.)

New Discovery Could Improve Organic Solar Cell Performance

Image - In this image, an optically excited spin-singlet state (red), which features electron-hole pairs, splits into a pair of spin-triplet states (blue). The individual triplets have equal and opposite center-of-mass momenta – they behave like waves moving in opposite directions along a crystal. The gray and white spheres represent carbon and hydrogen atoms, respectively. (Credit: Florian Brown-Altvater/Berkeley Lab)
