Abstract: ainihin tsarin tsari da kuma ka'idojin aiki na wayar salula (Safiyo) An gabatar da matsayin tsarin tsarin tsarin na tsarin, an taƙaita matsayin matsayin bincike na yanzu, kuma ci gaban APD na gaba yana cikin bincikenci.
1. Gabatarwa
Mai daukar hoto shine na'urar da ta canza alamomin haske cikin siginar lantarki. A cikinPhotiontor, Cajin da aka kirkiro da daukar hoto ya yi farin ciki da Pidarfin da ya faru da Pishon ya shiga wurin taron daga cikin abin da aka yi amfani da shi kuma ya samar da hoton hoto. Ko da a matsayin mafi girman martani, pinodiode na iya samar da nau'i biyu na dami biyu na lantarki a mafi yawan, wanda shine na'urar ba tare da riba ba. Don mafi girman martani, ana iya amfani da hoto mai amfani da hoto. Tasirin amplification na APD akan hoto ya dogara ne akan tasirin ionization. A karkashin wasu yanayi, karancin wutan lantarki da ramuka na iya samun isasshen makamashi don yin karo tare da lattice don samar da sabon nau'i biyu na nau'i-nau'i nau'i-nau'i. Wannan tsari shine hakkin sarkar, saboda biyu daga cikin rami na lantarki da aka kirkira ta hanyar sha da yawa na dami biyu kuma suna samar da babban hoto na biyu. Sabili da haka, apd yana da babban martani da ribar cikin gida, wanda ke inganta sinadarin siginar-don-amo na na'urar. APD za a yi amfani da shi a cikin nesa-nesa ko ƙananan tsarin file na fiber na fiberical tare da wasu iyakoki akan ikon da aka samu. A halin yanzu, masana na Pencalical na'urorin suna da kyau sosai game da tsammanin ci gaba, kuma yarda cewa binciken APD ya zama dole don haɓaka gasa ta duniya ta duniya.

2.1 kayan
(1)Sipportor
Fasahar Si Fasaha ita ce fasahar da aka yi amfani da ita a fagen microecronics, amma bai dace da shirye-shiryen na'urori ba a cikin kewayon da aka samu na 1.31mm da 1.55mm wanda aka yarda da shi gabaɗaya a fagen sadarwa na gani.
(2) GE
Kodayake amsawar gepdral ge a APD ta dace da bukatun low as asara da ƙarancin watsawa a cikin isar da Fiber, akwai manyan matsaloli a cikin shiri. Bugu da kari, kwamitin Ge da ramin ionization yana kusa da () 1, don haka yana da wahalar shirya manyan na'urorin APD APD.
(3) a0.53ga0.47as / inp
Hanya mai inganci ce don zaɓar A ciki0.53ga0.47as azaman hasken haske Layer na APD da inp kamar Layer mai yawa. Abubuwan ƙwanƙwasa na IN0.53Ga0.4sas abu shine 1.65mm, 1.31mm, abu mai tsada, wanda ya fi dacewa da abin da aka fi so don karin mai gano haske a halin yanzu.
(4)Ingeraas daukar hoto/ Insafiyo
Ta zaɓar Ingaasp a matsayin mai ɗaukar haske a matsayin mai yawa, APD tare da raira kwalliyar ruwa na 1-1.4mm, ana iya shirya riba mai kyau, mara kyau duhu kuma ana iya shirya riba mara nauyi. Ta hanyar zaɓar abubuwan da aka gyara daban-daban, ana samun mafi kyawun aikin takamaiman abubuwan igiyar ruwa.
(5) kanada / Inalas
A cikin0.52Al0.48As kayan yana da rata band (1.47ev) kuma baya shan kashi na kilogiram na 1.55mm. Akwai tabbacin cewa bakin ciki a cikin0.52Al0.48s Epitaxal Layer na iya samun mafi kyawun samun halaye fiye da inp mai yawa a ƙarƙashin yanayin allurar allon lantarki.
(6) Ingdaas / P) / Innaas da Ingaas / in (Al) Gaas / Inalas
Tasarin adadin kayan abu shine mahimmancin mahimmancin aiwatar da aikin APD. Sakamakon ya nuna cewa hadarin ionizize kudi na gabatar da Layer (P) / Innaalas da kuma Gais / Inalas Superlettote tsari. Ta amfani da tsarin Superlattice, injiniyan band zai iya sarrafa yanayin asymmetricy na zamani tsakanin takaddun wasan kwaikwayon (ΔEC >> ΔEv). Idan aka kwatanta shi da kayan balk, Ingaas / inalas Qutunsu Saboda Δec >> ΔEV, ana tsammanin ƙarfin da aka samu ta hanyar lantarki ya ƙara ƙimar ionization fiye da gudummawar makamashi mai ƙarfi zuwa matakin ionization (b). Matsakaicin (k) na ƙimar lantarki zuwa ƙimar ionize yana ƙaruwa. Sabili da haka, babban kayan maye (GBW) da ƙananan hayaniya za a iya samu ta hanyar amfani da tsarin Superlettice. Koyaya, wannan Ingaas / Indaas Quantum ingantacciyar tsari APD, wanda zai iya ƙara darajar K), yana da wuya a yi amfani da masu karba na zamani. Wannan saboda mahimmancin wanda ya shafi matsakaicin martani yana iyakance ta hanyar duhu na yanzu, ba hayaniya mai yawa ba. A cikin wannan tsarin, duhu na yanzu ana haifar da tasirin yin tasirin ingancin Ingaren, maimakon Ingdaas, a maimakon Ingdaas, a maimakon Ingdaas, a maimakon Ingdaas a matsayin rip Layer na Quantum da kyau tsarin zai iya hana duhu a halin yanzu.
