Cov kev nce qib tshiab kawg ntawm thev naus laus zisCov duab diodes avalanche
Avalanche photodiodes sawv cev rau cov thev naus laus zis tseem ceeb hauv cov optoelectronics niaj hnub no, txuas qhov sib txawv ntawm cov tsooscov duab diodesthiab cov raj photomultiplier. Lawv tuaj yeem muab qhov nce sab hauv los ntawm qhov cuam tshuam avalanche, yog li ua tiav qhov kev tshawb pom siab thaum tswj hwm qhov ruaj khov thiab compact ntawm cov khoom siv semiconductor.
Kev txhim kho tas mus li ntawmAPD Photodetectorthev naus laus zis, suav nrog kev nce qib hauv cov ntaub ntawv, kev tsim qauv thiab hom kev ua haujlwm, tau nthuav dav nws cov haujlwm thiab daim ntawv thov. Cov kev tshawb pom tshiab tshaj plaws hauv cov khoom siv bandwidth nce, kev tsim qauv tshaj lij rau cov kab wavelength tshwj xeeb, thiab kev txhim kho hauv cov yam ntxwv suab nrov tab tom thawb cov ciam teb ntawm qhov ua tau rau cov khoom siv no.
Cov kev nce qib tshiab hauv APDLub tshuab ntes duabthev naus laus zis suav nrog:
Cov khoom siv bandwidth siab heev: Cov kws tshawb fawb tau ua tiav germanium/silicon APD Photodetector nrog bandwidth nce siab tshaj 1 THz. Qhov kev tawg tshiab no tau ua tiav los ntawm kev tsim cov hluav taws xob faib tawm thiab tsim cov nyhuv resonance thaum lub sijhawm avalanche.
2. Kev tshawb pom qhov muag tsis pom kev zoo dua: Tus qauv tsim tshiab ntawm unipolar barrier qhia tau tias muaj qhov nce ntawm avalanche txog li 5.9 × 10^5 thiab muaj peev xwm tshawb pom ntawm 2.33 × 10^16 Jones hauv wafer-level ultraviolet APD.
3. Kev tswj hwm hluav taws xob tawg zoo dua: Cov txheej txheem tshiab rau kev tswj hwm hluav taws xob tawg suav nrog kev sib xyaw ua ke ntawm lub tshuab nqus hluav taws xob uas tsim ua ke nrog thaj chaw ntawm APD. Cov kev nce qib no tas li thawb cov ciam teb ntawm APD thev naus laus zis cov peev xwm, txhawb nqa cov ntawv thov tshiab thiab txhim kho kev ua haujlwm ntawm cov uas twb muaj lawm.
Nrog kev nce qib ntawm kev tshawb fawb, peb tuaj yeem cia siab tias yuav muaj kev txhim kho ntxiv ntawm APD Photodetector thev naus laus zis, tshwj xeeb tshaj yog nyob rau hauv cov cheeb tsam xws li kev txo suab nrov, kev nce bandwidth, kev txhim kho qhov rhiab heev thiab kev nthuav dav ntawm cov kev pabcuam. Cov kev txhim kho no yuav txuas ntxiv ua rau APD yog ib qho tseem ceeb hauv cov teb uas paub tab xws li kev sib txuas lus thiab cov teb tshiab xws li quantum technology, autonomous systems thiab advanced scientific instruments.
