InGaAs epitaxial wafer substrate PD Array fotodetector arrays nwere ike iji maka LiDAR

InGaAs epitaxial wafer substrate PD Array fotodetector arrays nwere ike iji maka onyonyo egosipụtara LiDAR

Nkọwa dị mkpirikpi:

InGaAs ihe nkiri epitaxial na-ezo aka na indium gallium arsenic (InGaAs) otu ihe nkiri kristal dị mkpa nke kpụrụ site na teknụzụ uto epitaxial n'otu mkpụrụ. Ngwa ngwa InGaAs epitaxial a na-ahụkarị bụ indium phosphide (InP) na gallium arsenide (GaAs). Ihe ndị a na-emepụta ihe nwere àgwà kristal dị mma na nkwụsi ike nke okpomọkụ, nke nwere ike inye ezigbo mkpụrụ maka uto nke InGaAs epitaxial layers.
PD Array (Photodetector Array) bụ ọtụtụ ihe nchọpụta foto nwere ike ịchọpụta ọtụtụ akara ngosi n'otu oge. A na-ejikarị mpempe akwụkwọ epitaxial toro site na MOCVD na fotodetection diodes, ihe mejupụtara absorption oyi bụ nke U-InGaAs, ndabere doping bụ <5E14, na Zn nwere ike mechaa site n'aka onye ahịa ma ọ bụ Epihouse. Ejiri PL, XRD na ECV nyochara mbadamba ihe epitaxial.

Akụkụ bụ isi nke InGaAs mpempe akwụkwọ epitaxial laser gụnyere

1. Lattice dakọtara: Enwere ike ịmekọrịta ihe nkedo dị mma n'etiti InGaAs epitaxial Layer na InP ma ọ bụ GaAs substrate, si otú ahụ na-ebelata njupụta nrụrụ nke oyi akwa epitaxial ma melite arụmọrụ nke ngwaọrụ ahụ.
2. Mgbanwe mgbanwe nke band: Enwere ike nweta ọdịiche nke band nke InGaAs site n'ịgbanwe nha nke components In na Ga, nke na-eme ka InGaAs epitaxial mpempe akwụkwọ nwee ọtụtụ atụmanya ngwa ngwa na ngwaọrụ optoelectronic.
3. High photosensitivity: InGaAs ihe nkiri epitaxial nwere mmetụta dị elu na ìhè, nke na-eme ka ọ dị n'ọhịa nke nchọpụta fotoelectric, nkwurịta okwu anya na uru ndị ọzọ pụrụ iche.
4. Nkwụsi ike dị elu: InGaAs / InP epitaxial Ọdịdị nwere ezigbo nkwụsi ike okpomọkụ dị elu, ma nwee ike ịnọgide na-arụ ọrụ ngwaọrụ kwụsiri ike na okpomọkụ dị elu.

Ngwa ndị bụ isi nke mbadamba ụrọ epitaxial laser InGaAs gụnyere

1. Optoelectronic ngwaọrụ: InGaAs mbadamba epitaxial nwere ike iji mepụta photodiodes, fotodetectors na ngwaọrụ ndị ọzọ optoelectronic, nke nwere ọtụtụ ngwa ngwa na nkwurịta okwu anya, ọhụụ abalị na ubi ndị ọzọ.

2. Lasers: InGaAs epitaxial sheets nwekwara ike iji rụpụta lasers, karịsịa lasers ogologo oge, nke na-arụ ọrụ dị mkpa na nkwukọrịta fiber optic, nhazi mmepụta ihe na mpaghara ndị ọzọ.

3. Mkpụrụ ndụ anyanwụ: InGaAs ihe nwere oke mgbanwe mgbanwe mgbanwe nke band, nke nwere ike izute ihe dị iche iche chọrọ site na cell photovoltaic thermal, ya mere InGaAs epitaxial mpempe akwụkwọ nwekwara ụfọdụ ngwa ngwa na ubi nke anyanwụ cell.

4. Ihe onyonyo ahụike: N'ime akụrụngwa onyonyo ahụike (dịka CT, MRI, wdg), maka nchọpụta na onyonyo.

5. Netwọk sensọ: na nlekota gburugburu ebe obibi na nchọpụta gas, enwere ike nyochaa ọtụtụ paramita n'otu oge.

6. Automation nke ụlọ ọrụ: eji na usoro ọhụụ igwe iji nyochaa ọnọdụ na àgwà nke ihe dị na akara mmepụta.

N'ọdịnihu, ihe onwunwe nke InGaAs epitaxial substrate ga-aga n'ihu na-emeziwanye, gụnyere mmelite nke mgbanwe mgbanwe fotoelectric na mbelata ọkwa mkpọtụ. Nke a ga-eme ka InGaAs epitaxial substrate nke a na-ejikarị eme ihe na ngwaọrụ optoelectronic, na arụmọrụ dị oke mma. N'otu oge ahụ, a ga-emeziwanye usoro nkwadebe ahụ mgbe niile iji belata ọnụ ahịa ma melite arụmọrụ, iji gboo mkpa nke nnukwu ahịa.

N'ozuzu, InGaAs epitaxial substrate nwere ọnọdụ dị mkpa n'ọhịa nke ihe semiconductor nwere njirimara pụrụ iche na atụmanya ngwa ngwa.

XKH na-enye nhazi nke InGaAs epitaxial sheets nke nwere usoro dị iche iche na ọkpụrụkpụ, na-ekpuchi ọtụtụ ngwa maka ngwaọrụ optoelectronic, lasers, na cell cell. A na-eji ngwá ọrụ MOCVD dị elu arụpụta ngwaahịa XKH iji hụ na arụmọrụ dị elu na ntụkwasị obi. N'ihe gbasara ngwa agha, XKH nwere ọtụtụ ụzọ isi iyi nke mba ụwa, nke nwere ike ijikwa ọnụ ọgụgụ nke iwu na-agbanwe agbanwe, ma nye ọrụ ndị bara uru dị ka nhazigharị na nkewa.
