Aluminum Nitride (AlN) Crystals

Featured Product from Fairfield Crystal Technology, LLC.


Fairfield Crystal Technology uses a unique patented process to produce our Aluminum Nitride (AlN) crystals. We produce single-crystal hexagonal material for a variety of device applications. We are currently offering 5 to 10mm diameter research grade substrates.

The most important area of interest for the AlN substrates is solid-state lighting for general illumination, followed by blue laser diodes for optical recording, high power and high frequency devices for telecommunication and radar applications, and UV detectors for various analytical applications, including detecting chemical and biological agents for homeland security applications.
