Semicera cov10x10mm Nonpolar M-plane Aluminium Substrateyog tsim los kom ua tau raws li qhov yuav tsum tau ua ntawm kev siv optoelectronic siab heev. Qhov no substrate nta ib tug nonpolar M-dav hlau kev taw qhia, uas yog ib qho tseem ceeb rau txo polarization los ntawm cov khoom xws li LEDs thiab laser diodes, ua rau txhim khu kev qha thiab efficiency.
Cov10x10mm Nonpolar M-plane Aluminium Substrateyog crafted nrog tshwj xeeb crystalline zoo, kom ntseeg tau qhov tsawg kawg nkaus tsis xws luag thiab superior structural kev ncaj ncees. Qhov no ua rau nws yog qhov kev xaiv zoo tshaj plaws rau kev loj hlob epitaxial ntawm cov yeeb yaj kiab zoo III-nitride, uas yog qhov tseem ceeb rau kev txhim kho cov khoom siv optoelectronic tom ntej.
Semicera's precision engineering xyuas kom txhua tus10x10mm Nonpolar M-plane Aluminium Substratemuaj cov thickness zoo ib yam thiab nto flatness, uas yog ib qho tseem ceeb rau cov yeeb yaj kiab tsis sib xws thiab kev tsim khoom siv. Tsis tas li ntawd, lub substrate lub compact loj ua rau nws haum rau ob qho tib si kev tshawb fawb thiab ntau lawm ib puag ncig, tso cai rau siv tau yooj yim nyob rau hauv ntau yam kev siv. Nrog nws zoo heev thermal thiab tshuaj stability, no substrate muab ib tug txhim khu kev qha lub hauv paus rau txoj kev loj hlob ntawm txiav-ntug optoelectronic technologies.
