2inch LED Sapphire substrate

Product Description

Bicrystalline substrates are used for the creation of the Josephson transitions on high-temperature superconductor films. The tapes for the bicrystals are grown onto a bicrystalline seed. The orientation of the wide plane is [1102] the growth direction being [1102].

The bicrystalline angle is equal to 2 × 14° [10] . The production of laser diodes and super-bright blue and green light-emitting diodes (LEDs)is in rapid development. Similar rapid growth is observed for their application fields – from traffic lights to the treatment of patients suffering.

Although there are lots substrates which are regarded as potential materials to replace Sapphire Substrate, it is still dominated in the substrates (for GaN LED growth) market, because of its reasonable price and relatively low mismatch.

Zhongju is capable of processing substrates according to customer needs. Currently, our sapphire substrate productions ranges from 2 to 12 inches with high quality and accurate orientation.
