Could atoms be reordered to enhance the performance of electronic devices? A surprising discovery about quantum wells by a team from @sandialabs.bsky.social , @uarkansas.bsky.social and @dartmouthcollege.bsky.social points to a promising answer.
Could Atoms Be Reordered to Enhance Electronic Devices?
Scientists looked at how an electrical charge would move through a barrier of silicon, germanium and tin, part a quantum well. They thought the electrical charge would move more slowly, but mobility p...

Electronic systems for planes must withstand vibrations and the shock of landing. The UA Power Group met those challenges to create a smaller, lighter silicon carbide-based system. Then they took it for a test flight. @uarkansas.bsky.social
Smaller, Lighter Electric Motor Developed for Airplane
A test flight proved that a smaller, more efficient silicon carbide-based motor drive system could replace a hybrid plane's traditional silicon-based system.
