ʻO Semicera10x10mm Nonpolar M-plane Aluminum Substrateua hoʻolālā maikaʻi ʻia e hoʻokō i nā koi koi o nā noi optoelectronic kiʻekiʻe. Hōʻike kēia substrate i kahi nonpolar M-plane orientation, he mea koʻikoʻi no ka hōʻemi ʻana i nā hopena polarization i nā mea hana e like me nā LED a me nā diodes laser, e alakaʻi ana i ka hoʻomaikaʻi ʻana i ka hana a me ka pono.
ʻO ka10x10mm Nonpolar M-plane Aluminum Substratehana ʻia me ka maikaʻi crystalline maikaʻi loa, e hōʻoiaʻiʻo ana i ka liʻiliʻi liʻiliʻi o nā hemahema a me ka maikaʻi o ke kūkulu ʻana. ʻO kēia ke koho maikaʻi loa no ka ulu ʻana o ka epitaxial o nā kiʻiʻoniʻoni III-nitride kiʻekiʻe, he mea nui ia no ka hoʻomohala ʻana i nā mea hana optoelectronic e hiki mai ana.
ʻO Semicera's precision engineering e hōʻoia i kēlā me kēia10x10mm Nonpolar M-plane Aluminum Substratehāʻawi i ka mānoanoa like ʻole a me ka palahalaha o ka ʻili, he mea koʻikoʻi no ka waiho ʻana o nā kiʻiʻoniʻoni like ʻole a me ka hana ʻana i nā mea hana. Hoʻohui ʻia, ʻo ka nui paʻa o ka substrate e kūpono ia no ka noiʻi a me nā kaiapuni hana, e ʻae ai i ka hoʻohana maʻalahi i nā ʻano noi. Me kona kūpaʻa wela a me ke kemika maikaʻi loa, hāʻawi kēia substrate i kahi kumu hilinaʻi no ka hoʻomohala ʻana i nā ʻenehana optoelectronic ʻokiʻoki.
