I-InGaAs epitaxial wafer substrate PD Array photodetector arrays ingasetshenziselwa i-LiDAR

I-InGaAs epitaxial wafer substrate PD Array photodetector array ingasetshenziselwa Isithombe Esifakiwe se-LiDAR

Incazelo emfushane:

Ifilimu ye-InGaAs ye-epitaxial ibhekisela ku-indium gallium arsenic (InGaAs) impahla yefilimu encane eyikristalu eyodwa eyakhiwe ubuchwepheshe bokukhula kwe-epitaxial ku-substrate ethile. Ama-epitaxial substrates ajwayelekile e-InGaAs yi-indium phosphide (InP) ne-gallium arsenide (GaAs). Lezi zinto ze-substrate zinekhwalithi enhle yekristalu nokuzinza kokushisa, okunganikeza i-substrate enhle kakhulu yokukhula kwezingqimba ze-InGaAs epitaxial.
I-PD Array (I-Photodetector Array) iwuxhaxha lwezithonjana zezithombe eziningi ezikwazi ukuhlonza amasignali amaningi okubona ngesikhathi esisodwa. Ishidi le-epitaxial elikhule lisuka ku-MOCVD lisetshenziswa kakhulu kuma-photodetection diode, isendlalelo sokumuncwa sakhiwe ama-U-InGaAs, i-doping yangemuva ingu-<5E14, kanti i-Zn esabalele ingagcwaliswa ikhasimende noma i-Epihouse. Amaphilisi e-epitaxial ahlaziywa ngezilinganiso ze-PL, XRD kanye ne-ECV.

Imininingwane Yomkhiqizo

Omaka bomkhiqizo

Izici ezibalulekile ze-InGaAs laser epitaxial sheet zihlanganisa

1. Ukufanisa i-lattice: Ukufanisa okuhle kwe-lattice kungafinyelelwa phakathi kwe-InGaAs epitaxial layer kanye ne-InP noma i-GaAs substrate, ngaleyo ndlela kuncishiswe ukuminyana kokukhubazeka kongqimba lwe-epitaxial futhi kuthuthukiswe ukusebenza kwedivayisi.
2. Igebe lebhendi elilungisekayo: Igebe lebhendi lempahla ye-InGaAs lingafinyelelwa ngokulungisa ingxenye yezingxenye ku-In ne-Ga, okwenza ishidi le-epitaxial le-InGaAs libe nohlu olubanzi lwamathemba okusebenza kumadivayisi we-optoelectronic.
3. I-photosensitivity ephezulu: Ifilimu ye-InGaAs ye-epitaxial inokuzwela okuphezulu ekukhanyeni, okuyenza ibe emkhakheni wokutholwa kwe-photoelectric, ukuxhumana kwe-optical nezinye izinzuzo eziyingqayizivele.
4. Ukuzinza okuphezulu kwezinga lokushisa: Isakhiwo se-InGaAs/InP epitaxial sinokuzinza okuhle kakhulu kwezinga lokushisa, futhi singagcina ukusebenza kwedivayisi okuzinzile emazingeni okushisa aphezulu.

Izinhlelo zokusebenza eziyinhloko ze-InGaAs laser epitaxial tablet zihlanganisa

1. Imishini ye-Optoelectronic: Amaphilisi e-InGaAs epitaxial angasetshenziswa ukwenza ama-photodiode, ama-photodetectors nezinye izisetshenziswa ze-optoelectronic, ezinohlelo olubanzi lwezinhlelo zokusebenza zokuxhumana nge-optical, ukubona ebusuku kanye neminye imikhakha.

2. Ama-Lasers: Amashidi e-InGaAs epitaxial angasetshenziswa futhi ukwenza ama-lasers, ikakhulukazi ama-lasers amagagasi amade, adlala indima ebalulekile ekuxhumaneni kwe-fiber optical, ukucutshungulwa kwezimboni kanye neminye imikhakha.

3. Amaseli elanga: Okubalulekile kwe-InGaAs kunobubanzi bokulungiswa kwegebe elibanzi, elingahlangabezana nezidingo zegebe lebhande elidingwa amaseli e-photovoltaic ashisayo, ngakho ishidi le-InGaAs epitaxial nalo linamandla athile okusebenza emkhakheni wamaseli elanga.

4. Isithombe sezokwelapha: Emishinini yokuthwebula yezokwelapha (efana ne-CT, i-MRI, njll.), ukuze kutholwe futhi kuthathwe izithombe.

5. Inethiwekhi yenzwa: ekuqaphelweni kwemvelo kanye nokutholwa kwegesi, amapharamitha amaningi angaqashwa kanyekanye.

6. I-Industrial automation: isetshenziswa ezinhlelweni zombono womshini ukuqapha isimo nekhwalithi yezinto emugqeni wokukhiqiza.

Ngokuzayo, izinto ezibonakalayo ze-InGaAs epitaxial substrate zizoqhubeka nokuba ngcono, okuhlanganisa ukuthuthukiswa kokusebenza kahle kokuguqulwa kwe-photoelectric kanye nokunciphisa amazinga omsindo. Lokhu kuzokwenza i-InGaAs epitaxial substrate isetshenziswe kabanzi kumadivayisi we-optoelectronic, futhi ukusebenza kuhle kakhulu. Ngesikhathi esifanayo, inqubo yokulungiselela izophinde ithuthukiswe ngokuqhubekayo ukuze kuncishiswe izindleko futhi kuthuthukiswe ukusebenza kahle, ukuze kuhlangatshezwane nezidingo zemakethe enkulu.

Ngokuvamile, i-InGaAs epitaxial substrate ithatha isikhundla esibalulekile emkhakheni wezinto ze-semiconductor ezinezici zayo eziyingqayizivele kanye namathemba okusebenza abanzi.

I-XKH inikezela ngokwenza ngendlela oyifisayo amashidi e-InGaAs epitaxial anezakhiwo nobukhulu obuhlukahlukene, afaka inhlobonhlobo yezinhlelo zokusebenza zemishini ye-optoelectronic, ama-laser, namaseli elanga. Imikhiqizo ye-XKH yakhiwe ngemishini ye-MOCVD ethuthukisiwe ukuze kuqinisekiswe ukusebenza okuphezulu nokuthembeka. Ngokuphathelene nokuhlelwa kwempahla, i-XKH inohlu olubanzi lwamashaneli omthombo wamazwe ngamazwe, angaphatha ngokuguquguquka inani lama-oda, futhi ahlinzeke ngamasevisi anenani elingeziwe njengokucolisiswa nokuhlukaniswa. Izinqubo zokulethwa ezisebenzayo ziqinisekisa ukulethwa ngesikhathi futhi zihlangabezana nezidingo zamakhasimende zekhwalithi nezikhathi zokulethwa.
