Dab tsi yog qhov sib txawv ntawm Led Epitaxial Wafers thiab LED Chips?

LED Epitaxial Wafer thiab LED Chip yog ob qhov tseem ceeb ntawm LED teeb kev thev naus laus zis, uas ua si sib txawv hauv cov txheej txheem tsim khoom ntawm LED. LED Epitaxial Wafer yog lub pob zeb ntawm LED manitting, uas muab cov khoom siv yooj yim rau kev tsim cov LED nti. Thiab LED nti yog qhov tseem ceeb ntawm LED Lub Teeb-Emitting.

I. Cov ntsiab lus ntxaws ntxaws ntxaws ntxaws

1. LED Epitaxial Wafer

LED epitaxial wafer yog ib hom ntawm substrate siv los cog cov qauv coj hauv kev tsim khoom. Nws ib txwm yog ua los ntawm tib cov ntaub ntawv siv lead ua, xws li gallium arsenide lossis gallium nitride. Cov tshuaj tiv thaiv kev nyab xeeb rau cov txheej txheem rau kev loj hlob ntawm cov khoom siv LED, thiab cov khoom lag luam semiconduct gown ntawm nws tsim cov qauv tseem ceeb ntawm LED. Cov txheej txheem no cuam tshuam cov thev naus laus zis thiab cov cuab yeej siv los xyuas kom meej tias qhov zoo ntawm cov wafer zoo ncaj qha ntsig txog qhov ua tau zoo ntawm cov khoom siv LED.

2. LED Chip

LED nti yog cov khoom tseem ceeb ntawm LED cov khoom, nws yog cov khoom me me uas hloov lub zog hluav taws xob rau hauv lub zog hluav taws xob. Nws muaj ntau lub pn junctions, uas emit ib qho xim tshwj xeeb ntawm lub teeb thaum muaj kev hla dhau ntawm lawv. Tus qauv tsim thiab tsim cov nti yog qhov tseem ceeb txuas hauv cov txheej txheem ntau lawm, uas txiav txim siab ua haujlwm ncaj qha ntawm LED xws li ci ntsa iab, kev ua tau zoo thiab lub neej.

3. Cov ntsiab lus ntawm qhov sib txawv

Lub ntsiab sib txawv ntawm ob yog tias LED Epitaxial wafer yog cov khoom siv LED teeb tsa raws li cov teeb tsa los ntawm cov qauv no. Kev tsim khoom ntawm epitaxial wafers tsom rau cov khoom zoo thiab ua tau zoo ntawm cov ntaub ntawv, thaum kev tsim khoom ntawm cov qauv tsim thiab kev paub txog kev paub txog cov txheej txheem. Nyob rau tib lub sijhawm, lawv cov haujlwm thiab cov xwm txheej thov tau sib txawv, cov ntaub ntawv muaj txiaj ntsig zoo los muab cov khoom siv yooj yim, thaum lub ntsej muag tau ncaj qha rau hauv Optoelectronic khoom los emit teeb.
