2. Application: Our sapphire substrate can be used as the substrate for the growth of III-V compounds such as GaN for LED's

A-Plane sapphire substrates - are usually used for hybrid microelectronic applications requiring a uniform dielectric constant and highly insulating characteristics.

C-Plane substrates - tend to be used for lll-V and ll-Vl compounds, such as GaN, for bright blue and green LED and laser diodes.

R-Plane substrates - these are preferred for the hetero-epitaxial deposition of silicon used in microelectronic IC applications.
