Electric Vehicle Batteries Could Get Big Boost With New Polymer Coating

Scientists at Berkeley Lab have developed a polymer coating that could enable longer lasting, more powerful lithium-ion batteries for electric vehicles. The advance opens up a new approach to developing EV batteries that are more affordable and yet easy to manufacture.

Harnessing Plant Molecules to Harvest Solar Energy

ROCKVILLE, MD – Our current solar panels aren’t very efficient; they are only able to convert up to about 20 percent of the sun’s energy into electricity. As a result, to generate a lot of electricity, the panels require a lot of space—sometimes leading forests to be cut down or farms to be replaced by solar.

2D Electronics Get an Atomic Tuneup

Scientists at Berkeley Lab have demonstrated a new technique that could improve the performance of atomically thin semiconductors for next-generation electronics such as optoelectronics, thermoelectrics, and sensors.

Design method may boost semiconductor performance by better handling heat

Finding ways to manage the flow of heat in silicon could boost the performance of semiconductors, but, so far, discovering the right design has remained elusive. Now, a team of Penn State researchers report that a fabrication technique may offer a path toward mastering the often chaotic flow of heat carriers at the nanoscale in silicon and other semiconductors.

Emerging Wide Bandgap Semiconductor Devices Based on Silicon Carbide May Revolutionize Power Electronics

Silicon plays a central role within the semiconductor industry for microelectronic and nanoelectronic devices, and silicon wafers of high purity single-crystalline material can be obtained via a combination of liquid growth methods. In Applied Physics Reviews, researchers describe the atomic mechanisms governing extended defect kinetics in cubic silicon carbide, which has a diamondlike zincblende crystal structure that manifests stacking and anti-phase instabilities. The study pinpoints the atomistic mechanisms responsible for extended defect generation and evolution.
