Product description
Patterned Sapphire Substrates (PSS) is micro-patterned sapphire substrate used to for GaN based light emitting diodes(LEDS). The PSS reduces the dislocation density in the GaN layer, enhances the light extraction efficiency and increase LEDs' brightness.

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.
