Semicera's10x10mm Nonpolar M-ndege Aluminium Substrateyakagadzirwa zvine hungwaru kuti isangane nezvinodiwa chaizvo zvepamberi optoelectronic application. Iyi substrate ine nonpolar M-ndege yekutarisa, iyo yakakosha kudzikisa polarization mhedzisiro mumidziyo yakaita se LEDs uye laser diode, zvichitungamira mukusimudzira mashandiro uye kugona.
The10x10mm Nonpolar M-ndege Aluminium SubstrateYakagadzirwa neyakasiyana-siyana yekristaro mhando, ichivimbisa kushoma kuremara densities uye yepamusoro yemaitiro kutendeseka. Izvi zvinoita kuti ive sarudzo yakanaka yekukura epitaxial yemhando yepamusoro III-nitride mafirimu, ayo akakosha pakuvandudzwa kwechizvarwa chinotevera optoelectronic zvishandiso.
Semicera's precision engineering inovimbisa kuti imwe neimwe10x10mm Nonpolar M-ndege Aluminium Substrateinopa ukobvu hunoenderana uye kupfava kwepasi, izvo zvakakosha pakuiswa kwemafirimu yunifomu uye kugadzira mudziyo. Pamusoro pezvo, iyo substrate's compact size inoita kuti ive yakakodzera kune ese ari maviri ekutsvagisa uye ekugadzira nharaunda, achibvumira kushandiswa kunoshanduka mumhando dzakasiyana dzekushandisa. Nekugadzikana kwayo kwakanyanya kupisa uye kemikari, iyi substrate inopa hwaro hwakavimbika hwekuvandudza tekinoroji yekucheka-kumucheto optoelectronic.
