Aluminium nitride

rWotD Episode 3366: Aluminium nitride Welcome to random Wiki of the Day, your journey through Wikipedia's vast and varied content, one random article at a time.The random article for Wednesday, 22 July 2026, is Aluminium nitride.Aluminium nitride (AlN) is a solid nitride of aluminium, which was first synthesized in 1862 by F. Briegleb and A. Geuther.AlN is a wide-bandgap semiconductor composed of aluminium and nitrogen. It crystallizes predominantly in the wurtzite structure and exhibits a direct band gap of approximately 6 eV at room temperature The exceptionally wide bandgap enables applications in deep-ultraviolet optoelectronics, while the material's thermal conductivity 321 W/(m·K), and strong polarization effects make it an important buffer and template material for III-nitride quantum heterostructures used in high-power and high-frequency electronic devices.This recording reflects the Wikipedia text as of 00:57 UTC on Wednesday, 22 July 2026.For the full current version of the article, see Aluminium nitride on Wikipedia.This podcast uses content from Wikipedia under the Creative Commons Attribution-ShareAlike License.Visit our archives at wikioftheday.com and subscribe to stay updated on new episodes.Follow us on Bluesky at @wikioftheday.com.Also check out Curmudgeon's Corner, a current events podcast.Until next time, I'm neural Danielle.
