Graphene Layered With Magnetic Materials Could Drive Ultrathin Spintronics

Photo - Andreas Schmid, left, and Gong Chen are pictured here with the spin-polarized low-energy electron microscopy (SPLEEM) instrument at Berkeley Lab that was integral to magnetic measurements of ultrathin samples that included graphene and magnetic materials.

Diamond ‘Spin-Off’ Tech Could Lead to Low-Cost Medical Imaging and Drug Discovery Tools

Photo - Microscopic images of diamond particles with nitrogen-vacancy defects. These samples, which exhibit a truncated octahedral shape, were used in experiments that sought new ways to tune and control an electronic property known as spin polarization. The scale bar at lower right is 200 microns (millionths of an inch). To the human eye, the pinkish diamonds resemble fine red sand. (Credit: Berkeley Lab, UC Berkeley)

Beyond the WIMP: Unique Crystals Could Expand the Search for Dark Matter

Image - A computerized simulation of the large-scale distribution of dark matter in the universe. An overlay graph (in white) shows how a crystal sample intensely scintillates, or glows, when exposed to X-rays during a lab test. This and other properties could make it a good material for a dark matter detector. (Credit: Millennium Simulation, Berkeley Lab)

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.)

X-Ray Experiments Suggest High Tunability of 2-D Material

Image - This rendering shows the atomic structure of a 2-D material ("ball-and-stick" representation at bottom) and the signature (middle and top) of electronic properties that were observed using an X-ray technique at Berkeley Lab’s MAESTRO beamline.

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)

X-Rays Reveal ‘Handedness’ in Swirling Electric Vortices

Image - Just as people can be left-handed or right-handed, scientists have observed chirality or "handedness" in swirling electric vortices in a layered material. (Credit: Pixabay)
