InGaAs epitaxial wafer substrate PD Array photodetector arrays tuaj yeem siv rau LiDAR

Lus piav qhia luv luv:

InGaAs epitaxial zaj duab xis hais txog indium gallium arsenic (InGaAs) ib leeg siv lead ua nyias zaj duab xis cov ntaub ntawv tsim los ntawm epitaxial kev loj hlob technology ntawm ib qho kev substrate. Common InGaAs epitaxial substrates yog indium phosphide (InP) thiab gallium arsenide (GaAs). Cov khoom siv substrate no muaj cov khoom siv lead ua zoo thiab thermal stability, uas tuaj yeem muab cov substrate zoo heev rau kev loj hlob ntawm InGaAs epitaxial txheej.
Lub PD Array (Photodetector Array) yog ib qho ntawm ntau lub photodetectors uas muaj peev xwm ntes tau ntau lub teeb liab kho qhov muag ib txhij. Daim ntawv epitaxial loj hlob los ntawm MOCVD feem ntau yog siv hauv photodetection diodes, cov txheej txheem nqus yog tsim los ntawm U-InGaAs, tom qab doping yog <5E14, thiab diffused Zn tuaj yeem ua tiav los ntawm cov neeg siv khoom lossis Epihouse. Cov ntsiav tshuaj epitaxial tau txheeb xyuas los ntawm PL, XRD thiab ECV ntsuas.

5. Sensor network: nyob rau hauv ib puag ncig saib xyuas thiab kuaj roj, ntau yam tsis tuaj yeem soj ntsuam ib txhij.

6. Muaj automation: siv nyob rau hauv lub tshuab tsis pom kev los saib xyuas cov xwm txheej thiab cov khoom zoo ntawm cov kab ntau lawm.

Nyob rau hauv lub neej yav tom ntej, cov khoom siv ntawm InGaAs epitaxial substrate yuav txhim kho ntxiv, nrog rau kev txhim kho ntawm photoelectric conversion efficiency thiab txo cov suab nrov. Qhov no yuav ua rau InGaAs epitaxial substrate siv dav hauv cov khoom siv optoelectronic, thiab kev ua tau zoo dua. Nyob rau tib lub sijhawm, cov txheej txheem kev npaj yuav kuj tseem ua kom zoo dua qub los txo cov nqi thiab txhim kho kev ua haujlwm, kom ua tau raws li qhov xav tau ntawm kev lag luam loj.

Feem ntau, InGaAs epitaxial substrate occupies ib qho tseem ceeb nyob rau hauv lub tshav pob ntawm semiconductor cov ntaub ntawv nrog nws cov yam ntxwv tshwj xeeb thiab dav daim ntawv thov prospects.

XKH muaj kev hloov kho ntawm InGaAs epitaxial nplooj ntawv nrog cov qauv sib txawv thiab tuab, npog ntau yam kev siv rau optoelectronic li, lasers, thiab solar cells. XKH cov khoom yog tsim nrog cov cuab yeej MOCVD siab heev kom ntseeg tau tias muaj kev ua haujlwm siab thiab kev ntseeg siab. Hais txog kev thauj mus los, XKH muaj ntau qhov chaw thoob ntiaj teb, uas tuaj yeem hloov kho tus naj npawb ntawm kev txiav txim, thiab muab cov kev pabcuam muaj nqis ntxiv xws li kev kho kom zoo thiab segmentation. Cov txheej txheem xa khoom tau zoo ua kom cov khoom xa tuaj raws sijhawm thiab ua tau raws li cov neeg siv khoom xav tau rau lub sijhawm zoo thiab xa khoom.
