HanyarRuwan hoto Hotoodiodeya yi kama da na PN Junction. Photoborector yana amfani da mafi yawan doped pn-jugtion, ƙarfin aiki dangane da ganowar APD yana da girma, kuma lokacin da aka ƙara nuna bambanci da yawan masu ganowa a cikin APD, kuma wasan kwaikwayon ya karu da hoto. Lokacin da APD yana cikin yanayin nuna bambancin, filin lantarki a cikin depletion Layer zai iya rabuwa da sauri da sauri kuma a ƙarƙashin aikin filin lantarki. Akwai yiwuwar cewa wayoyin lantarki za su yi karo cikin lattice yayin wannan tsari, haifar da wayoyin lantarki a cikin lattice don ionized. Ana maimaita wannan tsari, da ion ion kuma suna karo da lattice kuma yana haifar da adadin cajin caji a cikin APD don ƙaruwa, sakamakon shi a cikin babban halin yanzu. Wannan shine ainihin injin jiki a cikin APD cewa masu binciken APD suna da sifofin da sauri na sauri, manyan darajar yanzu da babban hankali. Idan aka kwatanta da PN-Junction da PIN Junction, APD yana da saurin amsawa, wanda shine saurin mayar da martani tsakanin bututun mai na yanzu.
(5) Schotty junction Photodepertor
Tsarin asalin Schottkyy junction Pippotector shine Schott schott Schott schott schott schott schotty ne, wanda halayen masu alaƙa suka yi kama da waɗanda suka bayyana a sama, kuma ba ta da tabbataccen tsari da kuma yanke hukunci tare da yanke shawara. A lokacin da ƙarfe tare da babban aiki da kuma semiconductor tare da ƙaramin aiki aiki tsari for Computer form form Schotty, kuma sakamakon ju ne jutani ne na schotty. Babban inji yana da ɗan kama da irin na PN, ɗaukar nau'in n-nau'in semicontucontucontucontitts a matsayin misali, lokacin da kayan lantarki guda biyu suna tuntuɓar ɓangaren biyu, abubuwan da ke tattare da na biyu na kayan biyu, waɗanda zaɓe a cikin semicondanction zasu bazu zuwa gefen ƙarfe. Mai watsa shirye-shirye suna tara gaba a ƙarshen ƙarshen ƙarfe, don haka za su lalata yanayin lantarki daga ƙarfe na ciki, kuma a ƙarshe ya isa ga yanki na lantarki, kuma a ƙarshe ya isa SchottKy Jigtion. A karkashin yanayi mai haske, yankin shinge kai tsaye yana ɗaukar haske kuma yana samar da masu ɗaukar nauyi a cikin yankin da ke buƙatar isa yankin junction. Idan aka kwatanta da PN-Junction, Photondetecor dangane da junkutar Schotty yana da saurin amsawa, kuma saurin amsawa na iya kaiwa matakin NS.
