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

Kev Piav Qhia Luv:

InP epitaxial substrate yog cov khoom siv tseem ceeb rau kev tsim APD, feem ntau yog cov khoom siv semiconductor tso rau ntawm lub substrate los ntawm kev siv tshuab epitaxial loj hlob. Cov ntaub ntawv siv feem ntau suav nrog silicon (Si), gallium arsenide (GaAs), gallium nitride (GaN), thiab lwm yam, nrog cov khoom zoo heev. Lub APD photodetector yog ib hom photodetector tshwj xeeb uas siv cov teebmeem avalanche photoelectric los txhim kho lub teeb liab nrhiav pom. Thaum cov photons tshwm sim rau APD, cov khub electron-hole raug tsim. Kev nrawm ntawm cov neeg nqa khoom no nyob rau hauv kev ua ntawm lub teb hluav taws xob yuav ua rau muaj ntau tus neeg nqa khoom, ib qho "avalanche effect", uas ua rau cov zis tam sim no loj hlob.
Cov wafers Epitaxial uas MOCvD cog yog qhov tseem ceeb ntawm cov ntawv thov avalanche photodetection diode. Cov txheej txheem nqus tau npaj los ntawm cov khoom siv U-InGaAs nrog keeb kwm yav dhau doping <5E14. Cov txheej txheem ua haujlwm tuaj yeem siv InP lossis InAlAslayer. InP epitaxial substrate yog cov khoom siv yooj yim rau kev tsim APD, uas txiav txim siab qhov ua tau zoo ntawm lub tshuab ntes teeb pom kev zoo. APD photodetector yog ib hom photodetector siab rhiab heev, uas siv dav hauv kev sib txuas lus, kev hnov thiab kev thaij duab.
