Crystal database The University of California at San Diego and Lawrence Berkeley National Laboratory have created an open-source database of elemental crystal surfaces and shapes. The database, called Crystalium, is a new and expanding set of information about various crystals. The database can help researchers design new materials for various applications, such as batteries, catalytic conv... » read more

Diamond polarimeters The Thomas Jefferson National Accelerator Facility (Jefferson Lab) has achieved what it says are the highest precision measurements of polarization in an atom smasher. The measurements were conducted with an instrument called a Hall C Compton Polarimeter. The polarimeter makes use of electron-photon scattering techniques and diamond-based microstrip detectors. The g... » read more

Etching superconducting materials Superconductors are devices that have zero electrical resistance, making them attractive for a range of applications. But superconductors must be cooled down to temperatures at or near absolute zero on the Kelvin scale to work. This, in turn, limits their applications. Absolute zero equates to −273.15° on the Celsius scale and −459.67° on the Fahrenheit ... » read more

CD-SAXS makes progress For years, chipmakers have used metrology tools based on various optical techniques, such as scatterometry. But optical-based scatterometry may one day run out of steam, prompting the need for a possible replacement. One long-awaited candidate is called X-ray scattering. There are various flavors of X-ray scattering, including CD small-angle X-ray scattering (CD-SAXS)... » read more

Black phosphorus photodetectors Phosphorus, a highly reactive element commonly found in match heads, tracer bullets, and fertilizers, can be turned into a stable crystalline form known as black phosphorus. In a new study, researchers from the University of Minnesota used an ultrathin black phosphorus film 20 atoms thick to demonstrate high-speed data communication on nanoscale optical circui... » read more
