2inch 3inch 4inch InP epitaxial wafer substrate APD lub teeb ntes rau kev sib txuas lus fiber ntau lossis LiDAR

Lus piav qhia luv luv:

InP epitaxial substrate yog cov khoom siv rau kev tsim APD, feem ntau yog cov khoom siv semiconductor tso rau hauv substrate los ntawm epitaxial kev loj hlob technology. Cov ntaub ntawv siv feem ntau suav nrog silicon (Si), gallium arsenide (GaAs), gallium nitride (GaN), thiab lwm yam, nrog rau cov khoom siv hluav taws xob zoo heev. APD photodetector yog ib hom tshwj xeeb ntawm photodetector uas siv cov nyhuv avalanche photoelectric los txhim kho cov teeb liab pom. Thaum photons tshwm sim ntawm APD, electron-qhov khub raug tsim. Lub acceleration ntawm cov cab kuj nyob rau hauv qhov kev txiav txim ntawm ib tug hluav taws xob teb tej zaum yuav ua rau cov tsim ntawm ntau cov cab kuj, ib tug "avalanche effect", uas ua rau kom cov zis tam sim no.
Epitaxial wafers zus los ntawm MOCvD yog lub hom phiaj ntawm avalanche photodetection diode daim ntaub ntawv. Cov txheej txheem nqus tau npaj los ntawm U-InGaAs cov ntaub ntawv nrog keeb kwm yav dhau los doping <5E14. Cov txheej txheem ua haujlwm tuaj yeem siv InP lossis InAlAslayer. InP epitaxial substrate yog cov khoom siv tseem ceeb rau kev tsim APD, uas txiav txim siab qhov ua tau zoo ntawm cov khoom siv kho qhov muag. APD photodetector yog ib hom kev ntsuas siab siab photodetector, uas yog siv dav hauv kev sib txuas lus, kev paub thiab kev kos duab.

Cov yam ntxwv tseem ceeb ntawm InP laser epitaxial ntawv suav nrog

1. Band gap yam ntxwv: InP muaj qhov nqaim band sib txawv, uas yog tsim rau ntev-yoj infrared teeb pom kev, tshwj xeeb tshaj yog nyob rau hauv lub wavelength ntau ntawm 1.3μm mus rau 1.5μm.
2. Kev ua haujlwm kho qhov muag: InP epitaxial zaj duab xis muaj qhov ua tau zoo kho qhov muag, xws li lub zog luminous thiab sab nraud quantum efficiency ntawm qhov sib txawv wavelengths. Piv txwv li, ntawm 480 nm, lub zog luminous thiab sab nraud quantum efficiency yog 11.2% thiab 98.8%, feem.
3. Carrier dynamics: InP nanoparticles (NPs) nthuav tawm ob chav exponential decay cwj pwm thaum lub sij hawm epitaxial loj hlob. Lub sij hawm tawg sai yog vim muaj kev txhaj tshuaj rau hauv InGaAs txheej, thaum lub sij hawm qeeb qeeb yog cuam tshuam rau cov cab kuj sib txuas hauv InP NPs.
4. Cov yam ntxwv kub kub: AlGaInAs / InP quantum zoo cov khoom muaj kev ua tau zoo ntawm qhov kub thiab txias, uas tuaj yeem tiv thaiv cov dej ntws tawm thiab txhim kho cov yam ntxwv kub ntawm lub laser.
5. Cov txheej txheem tsim khoom: InP epitaxial sheets feem ntau yog cog rau ntawm lub substrate los ntawm molecular beam epitaxy (MBE) lossis hlau-organic chemical vapor deposition (MOCVD) technology kom ua tiav cov yeeb yaj kiab zoo.
Cov yam ntxwv no ua rau InP laser epitaxial wafers muaj cov ntawv thov tseem ceeb hauv kev sib txuas lus fiber ntau, quantum tseem ceeb faib thiab chaw taws teeb kho qhov muag.

Cov ntawv thov tseem ceeb ntawm InP laser epitaxial ntsiav tshuaj suav nrog
