Probing dopant distribution

DOE/Lawrence Berkeley National Laboratory
Peer-Reviewed Publication

Berkeley Lab researchers at the Molecular Foundry have shown that when doping a semiconductor to alter its electrical properties, equally important as the amount of dopant is how the dopant is distributed on the surface and throughout the material.

Edgy look at 2-D molybdenum disulfide

DOE/Lawrence Berkeley National Laboratory
Peer-Reviewed Publication

Berkeley Lab researchers have recorded the first observations of a strong nonlinear optical resonance along the edges of single layers of molybdenum disulfide that could be key to the use of this and similar 2-D semiconductors in future nanoelectronic devices

NERSC, Cray, Intel to collaborate on next-generation supercomputer for science

DOE/Lawrence Berkeley National Laboratory
Business Announcement

The US Department of Energy's National Energy Research Scientific Computing Center and Cray Inc. announced today that they have signed a contract for a next generation of supercomputer to enable scientific discovery. This agreement is a significant step in advancing supercomputing design toward the kinds of computing systems we expect to see in the next decade as we advance to exascale.

A glassy look for manganites

DOE/Lawrence Berkeley National Laboratory
Peer-Reviewed Publication

Researchers at Berkeley Lab's Advanced Light Source discovered a glass-like re-ordering of electron-spin states as manganite crystals recovered from a photo-excited conductor state back to an insulator state. The discovery holds promise for future ultrafast electronic switching and memory devices.

First size-based chromatography technique for the study of living cells

DOE/Lawrence Berkeley National Laboratory
Peer-Reviewed Publication

Using nanodot technology, Berkeley Lab researchers demonstrated the first size-based form of chromatography for studying the membranes of living cells. This unique physical approach to probing cellular membrane structures reveals critical information that can't be obtained through conventional microscopy.

Scientists capture ultrafast snapshots of light-driven superconductivity

DOE/SLAC National Accelerator Laboratory

A new study, based on an experiment at SLAC's X-ray laser, pins down a major factor behind the appearance of superconductivity -- the ability to conduct electricity with 100 percent efficiency -- in a promising copper-oxide material.

BOSS quasars track the expanding universe -- most precise measurement yet

DOE/Lawrence Berkeley National Laboratory
Peer-Reviewed Publication

Lawrence Berkeley National Laboratory scientists and their colleagues have made novel measurements of the structure of the universe when it was only about 3 billion years old, using quasars collected by the Baryon Oscillation Spectroscopic Survey (BOSS). Results include the most precise measurement of expansion since galaxies formed. BOSS, the largest component of the third Sloan Digital Sky Survey, pioneered the use of quasars to chart universal expansion and the role of dark energy.
