GaAs nwere ike dị elu nke epitaxial wafer substrate gallium arsenide wafer ike laser wavelength 905nm maka ọgwụgwọ laser

Nkọwa Dị Mkpirikpi:

Mpempe akwụkwọ epitaxial laser GaAs na-ezo aka na otu ihe nkiri kristal dị gịrịgịrị nke e ji teknụzụ uto epitaxial mepụta na gallium arsenide (GaAs) substrate, nke a na-eji emepụta ngwaọrụ optoelectronic dị ka lasers.
Igwe laser ike GaAs 905 na igwe epitaxy ike dị elu nke GaAs bụ laser dabere na ihe gallium arsenide (GaAs) ma a na-ejikwa ha nke ọma n'ọtụtụ ubi. A na-ejikarị igwe epitaxial MOCVD eme ihe na diode laser ike dị elu. A na-eji olulu quantum InGaAs dị ka oyi akwa na-arụ ọrụ. A na-enyocha wafer epitaxial site na PL, XRD, ECV na ụzọ nnwale ndị ọzọ. A na-eji laser ike GaAs 905 na chips epitaxy ike dị elu nke GaAs eme ihe nke ọma na ahụike, ụlọ ọrụ mmepụta ihe, nyocha sayensị na mpaghara ndị ọzọ n'ihi arụmọrụ dị elu ha, mmepụta ike dị elu na arụmọrụ okpomọkụ dị mma, ma nwee uru ahịa dị mkpa na ikike teknụzụ.

Isi ihe dị na mpempe akwụkwọ epitaxial laser GaAs gụnyere:

1. Njem elektrọn dị elu: Gallium arsenide nwere nnukwu ngagharị elektrọn, nke na-eme ka wafers epitaxial nke GaAs laser nwee ezigbo ojiji na ngwaọrụ ugboro ugboro na ngwaọrụ elektrọn dị elu.
2. Ọkụ ọkụ mgbanwe nke bandgap ozugbo: Dịka ihe eji eme bandgap kpọmkwem, gallium arsenide nwere ike ịgbanwe ike eletriki nke ọma ka ọ bụrụ ike ọkụ na ngwaọrụ optoelectronic, na-eme ka ọ dị mma maka imepụta laser.
3. Ogologo Wavelength: Laser GaAs 905 na-arụkarị ọrụ na 905 nm, nke na-eme ka ha dabara adaba maka ọtụtụ ojiji, gụnyere biomedicine.
4. Arụmọrụ dị elu: site na nnukwu arụmọrụ mgbanwe fotoelectric, ọ nwere ike ịgbanwe ike eletrik ka ọ bụrụ mmepụta laser nke ọma.
5. Mmepụta ike dị elu: Ọ nwere ike nweta mmepụta ike dị elu ma dabara adaba maka ọnọdụ ngwa nke chọrọ isi iyi ọkụ siri ike.
6. Ezigbo arụmọrụ okpomọkụ: Ihe GaAs nwere ezigbo njikwa okpomọkụ, na-enyere aka belata okpomọkụ ọrụ nke laser ma melite nkwụsi ike.
7.Nhazi sara mbara: Enwere ike ịgbanwe ike mmepụta site na ịgbanwe ọkụ draịva ka ọ dabara na ihe achọrọ maka ngwa dị iche iche.

Ngwa ndị bụ isi nke mbadamba epitaxial laser GaAs gụnyere:

1. Nkwukọrịta eriri anya: Enwere ike iji mpempe akwụkwọ epitaxial laser GaAs mepụta lasers na nkwukọrịta eriri anya iji nweta nnyefe mgbaàmà anya dị elu na nke dị anya.

2. Ngwa ụlọ ọrụ mmepụta ihe: N'ọhịa ụlọ ọrụ mmepụta ihe, enwere ike iji mpempe akwụkwọ epitaxial laser GaAs maka nhazi laser, akara laser na ngwa ndị ọzọ.

3. VCSEL: Laser oghere dị n'elu oghere kwụ ọtọ (VCSEL) bụ ihe dị mkpa maka ngwa nke GaAs laser epitaxial sheet, nke a na-ejikarị eme ihe na nkwukọrịta anya, nchekwa anya na mmetụta anya.

4. Infrared na spot field: Enwere ike iji akwụkwọ epitaxial laser GaAs mepụta infrared lasers, spot generators na ngwaọrụ ndị ọzọ, na-arụ ọrụ dị mkpa na nchọpụta infrared, ngosipụta ọkụ na ubi ndị ọzọ.

Nkwadebe nke mpempe akwụkwọ epitaxial laser GaAs dabere na teknụzụ uto epitaxial, gụnyere ihe nchekwa vapor metal-organic (MOCVD), molecular beam epitaxial (MBE) na ụzọ ndị ọzọ. Usoro ndị a nwere ike ijikwa ọkpụrụkpụ, nhazi na nhazi kristal nke oyi akwa epitaxial iji nweta mpempe akwụkwọ epitaxial laser GaAs dị elu.

XKH na-enye nhazi nke mpempe akwụkwọ epitaxial GaAs n'ụdị na ọkpụrụkpụ dị iche iche, na-ekpuchi ọtụtụ ngwa na nkwukọrịta anya, VCSEL, infrared na ubi ntụpọ ìhè. A na-emepụta ngwaahịa XKH site na ngwa MOCVD dị elu iji hụ na arụmọrụ dị elu na ntụkwasị obi dị elu. N'ihe gbasara nhazi, XKH nwere ọtụtụ ọwa isi mmalite mba ụwa, nke nwere ike ijikwa ọnụọgụ nke iwu n'ụzọ dị mfe, ma nye ọrụ bara uru dịka mmezi na nkewa. Usoro nnyefe dị irè na-eme ka nnyefe n'oge ma mezuo ihe ndị ahịa chọrọ maka ịdị mma na oge nnyefe. Ndị ahịa nwere ike ịnweta nkwado teknụzụ zuru oke na ọrụ mgbe eresịrị ngwaahịa ahụ iji hụ na ejiri ngwaahịa ahụ mee ihe nke ọma.
