Avalanche photodiode ua haujlwm txoj cai. Avalanche breakdown ua qhov chaw thaum lub diode raug rau siab rov qab voltageQhov rov qab tsis zoo voltage ua rau hluav taws xob hla ntawm txheej depletion. Lub teeb xwm txheej nkag mus rau thaj tsam p + thiab txuas ntxiv tau nqus mus rau thaj tsam p siab heev.
Photodiode ua haujlwm li cas?
A photodiode yog tus qauv PIN lossis p-n hlws ris. Thaum lub photon ntawm lub zog txaus tawm tsam lub diode, nws tsim ib qho hluav taws xob-qhov khubCov txheej txheem no tseem hu ua cov nyhuv photoelectric sab hauv. … Yog li lub qhov txav mus rau lub anode, thiab electrons mus rau cathode, thiab photocurrent raug tsim.
Lub hauv paus ntsiab lus ntawm kev ua haujlwm ntawm APD yog dab tsi?
The APD (avalanche photodiode) yog lub siab-ceev, siab-rhiab heev photodiode uas internally multiplies photocurrent thaum thim rov qab voltage yog thovCov kev ua haujlwm sab hauv hu ua avalanche multiplication nta siab photosensitivity uas ua rau kev ntsuas ntawm cov teeb liab qis qis.
Dab tsi yog lub luag haujlwm ntawm avalanche diode?
Ib lub avalanche diode yog ib hom khoom siv hluav taws xob tshwj xeeb tsim los ua haujlwm hauv thaj tsam rov qab. Cov diodes no yog siv los ua cov twj tso kua mis uas siv rau kev tswj lub kaw lus lub siab los tiv thaiv cov tshuab hluav taws xob los ntawm cov hluav taws xob ntau dhauLub cim ntawm lub diode no yog tib yam li Zener diode.
Qhov zoo ntawm avalanche photodiode yog dab tsi?
Qhov zoo ntawm avalanche photodiode:
Includes a ntau dua qib ntawm rhiab heev . Kev ua haujlwm siab . lub sijhawm teb nrawm.
