IiSemicera's10x10mm Nonpolar M-plane yeAluminiyam Substrateiyilwe ngobunono ukuhlangabezana neemfuno ezithe ngqo ze-optoelectronic applications. Le substrate ine-nonpolar M-plane orientation, ebaluleke kakhulu ekunciphiseni iziphumo ze-polarization kwizixhobo ezifana ne-LED kunye ne-laser diode, ekhokelela ekusebenzeni okuphuculweyo kunye nokusebenza kakuhle.
I10x10mm Nonpolar M-plane yeAluminiyam Substrateyenziwe ngomgangatho obalaseleyo wekristale, iqinisekisa ukuxinana okuncinci kunye nomgangatho ophezulu wesakhiwo. Oku kwenza kube yinto efanelekileyo yokukhula kwe-epitaxial yeefilimu eziphezulu ze-III-nitride, eziyimfuneko ekuphuhliseni izixhobo ze-optoelectronic zesizukulwana esilandelayo.
Ubunjineli obuchanekileyo beSemicera buqinisekisa ukuba nganye10x10mm Nonpolar M-plane yeAluminiyam Substrateinikeza ubukhulu obungaguquguqukiyo kunye nokuthe tyaba komphezulu, ezibalulekileyo ekubekweni kwefilim efanayo kunye nokuyilwa kwesixhobo. Ukongeza, ubungakanani be-substrate obuncinci buyenza ifaneleke kuzo zombini iindawo zophando kunye nemveliso, evumela ukusetyenziswa okuguquguqukayo kwizicelo ezahlukeneyo. Ngokuzinza kwayo okuhle kakhulu kwe-thermal kunye neekhemikhali, le substrate ibonelela ngesiseko esithembekileyo sokuphuhliswa kobuchwepheshe be-optoelectronic.
