Nitride Crystals, Inc. manufactures substrates for a broad range of III-nitride devices. These include Graphene-on-SiC products and conducting low-micropipe density and micropipe-free SiC substrates. Nitride Crystals, Inc. is also offering SiC Lely crystals in a variety of difficult-to-find polytypes for the researcher interested in exploring the behavior of various SiC polytypes.
Both conducting, low-micropipe and micropipe-free 4H- and 6H-SiC wafers are being manufactured in 2” and 3” diameters. 4” diameter 4H-SiC is under development. Currently Nitride Crystals, Inc. has no plans to develop semi-insulating SiC.
Nitride Crystals, Inc. has available a stock of high-quality Lely crystals of various polytypes. The supply of the more rare polytypes is limited; however, they offer an opportunity for scientists to explore the properties of SiC polytypes that are not commonly available.
