With the recent announcement by Infineon that GaN use is reaching the “tipping point” for accelerated adoption, maybe it’s ...

New research from materials scientist Chris Van de Walle illuminates the path to superior electro-optic performance in ...

In the search for silicon-compatible materials, aluminum scandium nitride (AlScN), which had already been flagged as an excellent piezoelectric—referring to a material's ability to generate ...

Titanium aluminum nitride alloys (TiAlN) were grown by magnetron sputtering—a highly controlled and repeatable physical vapor deposition process. However, sputter-depositing these coatings on ...

This is a false-color SEM image of a NEMS resonator. A freestanding aluminum nitride (AlN) nanoplate (the central rectangular green plate), released from the underlying silicon substrate, is supported ...

coated with a 100 nm thick silicon nitride anti-reflective layer on the front side and a 20 µm thick layer of aluminum on the back side, both stripped with silver electrodes approximately 30 μm ...

Alternative materials include cast iron and refractory ceramics, silicon carbide and aluminum titanate. Sialon is an alloy of silicon nitride and offers superior thermal and mechanical properties.
