Ubushakashatsi bugezweho bwaAvalanche Photodetetector

Ikoranabuhanga rya infrad rikoreshwa cyane muri revonnisasion ya gisirikare, gukurikirana ibidukikije, kwisuzumisha kwa muganga nibindi bice. Ibitekerezo gakondo byiburasirazuba bifite aho bigarukira mubikorwa, nko kwiyumvisha ibintu, umuvuduko wo gusubiza nibindi. INAS / INASS COSTB II elelattice (T2SL) ibikoresho bifite imitungo myiza ya Phofetericlic na Tantiction, bikaba byiza mugihe kirekire cyane (Lwir). Ikibazo cyigisubizo gifite intege nke mu kumenya infrard ndende yabaye impungenge igihe kirekire, gigabanya cyane kwizerwa cyibikoresho bya elegitoroniki. Nubwo Avalanche Photodetetector (APD Photodetetector) Ifite imikorere myiza yo gusubiza, ibabazwa numwijima mwinshi mugihe cyo kugwira.

Gukemura ibyo bibazo, itsinda ryaturutse muri kaminuza ya elegitoronike n'ikoranabuhanga rya China by'Ubushinwa ryashizeho neza icyiciro cyimikorere ya II exlattice II elllattice (T2SL) igihe kirekire - umuhengeri w'amashure (apd). Abashakashatsi bakoresheje igipimo cyo hasi cyo kwizihiza kinas / inassb t2sl absorber layer kugirango ugabanye umwijima. Muri icyo gihe, alasb hamwe nagaciro gato k gakoreshwa nkikibanza cyo kugwiza kugirango uhagarike urusaku rwibikoresho mugihe ukomeza inyungu zihagije. Iyi pried itanga igisubizo kizere cyo guteza imbere iterambere ryikoranabuhanga rirerire rya leta. Ubwumvikane bwerekana igishushanyo mbonera, kandi muguhindura igipimo cyahimbwe inas na inassb, inzibacyuho yoroshye yitsinda iragerwaho, kandi imikorere ya detector iratera imbere. Kubijyanye no gutoranya ibintu no gutegura, ubu bushakashatsi busobanura muburyo burambuye uburyo bwo gukura no gutunganya ibipimo bya inas / in2sl ibikoresho bya T2SL bikoreshwa mugutegura detector. Kugena ibihimbano hamwe nubunini bwa inas / inassl ni ihinduka rikomeye kandi rya parameter rirasabwa kugirango ugere ku ntera. Mu rwego rwo kuramba, kugirango ugere ku burebure bumwe bwo gukata nka inas / gasb t2sl, igicucu cya in2sl, insmu t2sl igihe kimwe gisabwa. Nyamara, monocycle yijimye biva mu kugabanuka kwinjiza neza mu cyerekezo cyo gukura no kwiyongera mu mwobo ufatika muri T2SL. Iraboneka ko kongeramo ibice bya SB bishobora kugeraho uburebure burebire butagaragara neza cyane mugihe gito. Nyamara, ibigize urusiporo birenze urugero birashobora gutuma habaho gutandukanya ibintu bya SB.

Kubwibyo, INAS / INAS0.5SB0.5 T2SL hamwe nitsinda rya SB 0.5 ryatoranijwe nkikirenga cya APDPhotodetetector. INAS / INASB T2SL ikura ahanini kuri GASB ishyari, bityo uruhare rwa GASB mu micungire ya Strain igomba gusuzumwa. Mubyukuri, kugera kuri strain equilibrium bikubiyemo kugereranya icyambu cyose gihoraho cya superlattice mugihe kimwe na lattice ihoraho ya substrate. Mubisanzwe, indwara ya tensile muri inas yishyurwa na streression yatangijwe na insassb, bikavamo urwego rubyimbye kuruta urwego rwa INASB. Ubu bushakashatsi bwapimweho igisubizo cya Phofeterictric ya Photofectics Photodetetector, harimo igisubizo nyaburanga, urusaku rwijimye, urusaku, kandi rugenzure imikorere yikigereranyo cya Gradient Cleers. Ingaruka zo kugwiza pulanche ya fotodetetector ya Avalanche irasesengurwa, kandi umubano uri hagati yimpamvu yo kugwiza hamwe nimbaraga zumucyo, ubushyuhe nibindi bipimo biraganirwaho.
