Notes:
(1) GaN is not available as a crystal, for reference only. (2) Not recommended for MOCVD because of low melting point.
Sizes and Orientations Available
Because each crystal is unique, maximum sizes and orientations available will vary. Please contact us for crystals for your specific requirements.
Applications
Blue LEDs, LASERS
