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.

A Leap in Using Silicon for Battery Anodes

Scientists have come up with a novel way to use silicon as an energy storage ingredient. They’ve developed a nanostructure incorporating carbon nanotubes to strengthen the material and modify the way silicon interacts with lithium, a key component in batteries used in electric cars and other devices.
