ʻAno oʻO ka polokalamu kiʻi PhotoDetETʻano
Kiakikohe mea hana e hoʻohuli ai i ka hōʻailona optical i loko o ka hōʻailona uila,ʻo kānaʻano a me nāʻano a me nāʻano'ē aʻe, hiki ke hoʻokaʻawaleʻia i loko o nā wahi likeʻole:
(1) Photoconduction photodettector
Ke hōʻikeʻia nei nā mea kiʻi kiʻi kiʻi i ka mālamalama, hoʻonui ka mea lawe kiʻi kiʻi kiʻi i ko lākou ola a hoʻemi i ko lākou paleʻana. Ua hauʻoli ka poʻe mea mālama i ka mahana o ka lumi ma lalo o keʻano ma lalo o ka hana o kahi kahua uila, no laila e hana ana i kahi mea i kēia manawa. Ma lalo o keʻano o ke kukui, ua hauʻoli nā electrons a me ke hoʻololiʻana. I ka manawa like, hoʻopau lākou ma lalo o ka hana o kahi kahua uila e hana i kahi kiʻi paʻi. Hoʻonui ka laweʻana i nā mea lawe kiʻi kiʻi kiʻi i ka laweʻana i ka mea hana a no laila e hōʻemi ana i ke kū'ē. Hōʻike pinepineʻia nā kiʻi kiʻi kiʻi kiʻi kiʻi kiʻi nui a me nā pane nui loa i ka hana, akāʻaʻole hiki iā lākou ke pane i nā hōʻailona kiʻekiʻe-maʻamau, he lohi ka wikiwiki o nā noi
(2)Pn photodetector
Ua hoʻokumuʻiaʻo PNDETOTCT i ka hoʻopili ma waena o P-Type Semiconductor a me N-Type Semicornuctor. Ma mua o ke kauʻiaʻana o ke kamaʻilio, aia nā meaʻelua i kahi kūlanaʻokoʻa. ʻO ka pae Fermi ma P-Type Semiconductor kokoke loa i ke kihi o ka Band Valence I ka manawa like,ʻo ka pae o ka fux of the ninaninau i kaʻaoʻao o ka band e neʻe mauʻia a hiki i ka pae o nā meaʻelua. ʻO ka hoʻololiʻana o ke kūlana o ke KuhinaʻAmelika Hui PūʻIa a me ke anaʻana e hele pū me ke kāʻei o ka hui. ʻO ka PN TURCLES ma ke kaulike a he pae kiʻekiʻe fermi. Mai ka hiʻohiʻona o ka loiloi laweʻana i nā mea lawe laweʻana,ʻo ka hapa nui o nā mea lawe kālā ma P-Tycters he mau mea kūʻai aku i nā mea kūʻai aku i nā mea kūʻai aku i nā mea kūʻai aku i nā huahana I ka wā e hoʻopiliʻia ai nā meaʻelua, ma muli o kaʻokoʻa ma keʻano o ka laweʻana, e like me nā mea e pono ai keʻano o nā kelepona i loko o nā lua. ʻO ka wahi i waihoʻia e kaʻokoʻa i waihoʻia e ka diffusion a me nā lua e hana ana i ke kahua o ka mea lawena, ua pau ke kahe o ke kiʻi static. Kaulike kūloko kūloko.
Ke hōʻikeʻia ka pn junction i ka radiation kukui, ua neʻe ka ikaika o ka photon i ke kahu, a me ke kanaka lawe kiʻi kiʻiʻia,ʻo ia hoʻi ke kime photo Ma lalo o ka hana o ke kahua uila,ʻo ka electron a me ka hole a me ka lua a me ka poa a me ke kuhikuhi o ka mea lawe kiʻi kiʻi kiʻiʻia. ʻO kēia ka kumu kumu kumu o ka pn junction photodettector.
(3)Pi photodetector
ʻO Pickudiode kahi mea hana p-type a me nā mea likeʻole ma waena o ka mea i kauʻia ma waena o keʻano he mea maʻamau a iʻole nā mea haʻahaʻa loa. ʻO kāna hana hana hana e like me ka PN TUMCON, i ka wā e hōʻikeʻia ai kaʻaoʻao o ka uila i ke aniani ʻO ke ala e pāʻani ai wau e hoʻonui i ka laulā o ka pahu pahu, aʻo ka huakaʻi pane pololei o Pendeneka, ua hoʻopauʻo The GIISTSO BETERY ma mua o ka hoʻolahaʻana o ka mea hana pn ʻO nā mea lawe i waho ma waho o ka mea eʻohiʻia e ka mea e hoʻopiliʻia e ka mea e hoʻokaʻawaleʻia ma o ka neʻeʻana o ka neʻeʻana o ka neʻeʻana. ʻO ka mānoanoa o ka lalena ka haʻahaʻa loa o wau aʻo kāna kumu,ʻo ia ke mea e hoʻomaikaʻi ai i ka pane pane pane o ka mea hopu.
(4)APd photodetectorAvalanche PhotoDODOD
Ka mea hana oAvalanche PhotoDODODua like ia me ka mea o pn junction. Hoʻohana nuiʻia ka photodettector i keʻano o ka pulu manu, he nui ka hanaʻana o ka mea hopu e hoʻonui ai iā Apd I ka manawa aʻApelila keʻano o ka hanaʻana o ka pēpē Bias, e ikaika loa ke kahua uila ma ka kaila o kaʻoihana uila. Aia kahi hopena e pili ana i nā electrons i loko o ka pattice i kēia kaʻina hana, e hoʻokau i nā electrons i ka latting i loko o ka latting e alohaʻia. Ua hana houʻia kēia kaʻina hana, a me nā mea aloha i loko o ka lattice pū kekahi me ka lattice O no keia kanaka Hoʻoikaika kūʻokoʻa i loko o APD ua loaʻa i nā mea nānāʻo'Ahap-e pili ana i ka hoʻokūkū wikiwiki, he nui a me kaʻike kiʻekiʻe. Ua hoʻohālikelikeʻia me Pn Junction a me PIN Junction,ʻo APD kahi wikiwiki wikiwiki wikiwiki,ʻo ia ka wikiwiki wikiwiki i waena o nā kiʻi kiʻi kiʻi o kēia manawa.
(5) Schotky SchotKY PhotodETector
ʻO keʻano kumu o ka schotky kiʻi kiʻi kiʻi kiʻi kiʻi kiʻi kiʻi kiʻi kiʻiʻia, heʻano likeʻole nā hiʻohiʻona ma ka hana o ka PNTER. I ka wā e pili ana kahi kila me kahi hana kiʻekiʻe a me ka semiconductor i kahiʻano hana likeʻole, a ua hanaʻia kahi hana Scirente. ʻO ka mīkini nui nui e like me keʻano o ka Pn Junction, e lawe ana i nā seminconndcuct i nāʻanoʻelua o ka seminconstugesʻelua. E hoʻopau mau ana nā mea koho balota ma keʻano he mae o ka metala, no laila e hoʻopau i ka hana uila ma lalo o ka papa hana uila equilibrium, a hope loa i ka hana schotky Ma lalo o nā kūlana māmā,ʻo ka'āina paʻa e pili ana i ke aniani a hoʻonui i nā mea lawe uila i loko o ka wahi o ka PNTERCATERS e hiki ai i ka wahi o ka PNTGITER. Hoʻohālikelikeʻia me PN JUNCON, e pili ana ke kiʻi kiʻi ma ke kulaʻo Schotky
