Ni ikiSi fotodecteur
Bitewe n'iterambere ryihuse ry'ikoranabuhanga rigezweho, ibikoresho bipima foto, nk'igikoresho cy'ingenzi gipima foto, byagiye bimenyekana buhoro buhoro. Cyane cyane ibikoresho bipima foto (Si photodetector)icyuma gipima foto cya silikoni), bitewe n'imikorere myiza yazo n'ubushobozi bwazo bwo gukoresha ibintu byinshi, byakunze kwitabwaho cyane. Iyi nkuru izatanga ibisobanuro byimbitse ariko byoroshye kumva ku mahame shingiro, imiterere y'imiterere, imiterere y'ikoreshwa, n'iterambere ry'ejo hazaza ry'ibikoresho bipima foto bya silikoni kuri buri wese.
Ihame ry'ibanze rya Si photodetectors rishingiye ku ngaruka za photoelectric. Iyo photon zikubita ibikoresho bya semiconductor, hakorwa electron-hole pairs, ibyo bikaba amashanyarazi. Ibikoresho bya silicon bifite ubushobozi bwiza bwo kwinjiza urumuri, cyane cyane mu migozi igaragara n'iy'imirasire ya infrared, bityo bikaba bikwiriye cyane gukoreshwa nk'ibikoresho by'ibanze bya photodetectors. Ihame ry'imikorere rya Si photodetectors rishobora gusobanurwa mu ntambwe nyinshi: intera ya photon, ifata ya photon, ikora ry'umuyoboro n'umusaruro w'umuyoboro.
Ku bijyanye n'imiterere ya silicon photodetectors, ubusanzwe zigabanyijemo ibice byinshi by'ingenzi: urwego rwakira urumuri, urwego rw'ingufu n'urwego rwa electrode. Urwego rwakira urumuri rushinzwe kwinjiza urumuri rw'impanuka no gutanga ibikoresho, mu gihe urwego rw'ingufu rukoreshwa mu kongera umubare w'ibikoresho, bityo byongera ubushobozi bwo kumva. Urwego rwa electrode rushinzwe gukusanya ibikoresho no gukora ibimenyetso by'amashanyarazi. Imiterere yakozwe neza ishobora kongera imikorere ya icyuma gipima urumuri, nko kunoza imikorere y'ikoranabuhanga mu guhindura amashanyarazi no kugabanya urusaku.
Uburyo bwo gukoresha icyuma gipima imiterere y'amashusho cya silikoni buriho byinshi cyane, bukubiyemo ibintu byinshi nko gutumanaho, gufata amashusho, no kugenzura ibidukikije. Mu itumanaho ry'amashusho, icyuma gipima imiterere y'amashusho gikoreshwa mu kwakira ibimenyetso by'amashusho no kubihindura ibimenyetso by'amashanyarazi kugira ngo amakuru ahererekanywa vuba. Mu rwego rwo gufata amashusho, icyuma gipima imiterere y'amashusho cya Si gikunze gukoreshwa muri kamera za digitale na webcam kugira ngo gifashe gufata amashusho asobanutse neza. Ikigo gipima imiterere y'amashusho cya Si gishobora kandi gukoreshwa mu kugenzura ibidukikije, kikamenya imiterere y'ibidukikije binyuze mu kugenzura impinduka mu mucyo, nko kumenya aho imyanda ituruka.
Mu gihe kizaza, iterambere rya silicon photodetector rizagaragara cyane cyane muri ibi bikurikira. Udushya mu bikoresho twitezweho kongera imikorere y'ibikoresho bipima urumuri, nko gukoresha aloyi nshya cyangwa ibikoresho bivanze kugira ngo byongere ubushobozi bwo kwinjiza urumuri no kunoza imikorere ya quantum. Kunoza imiterere y'imiterere y'inyubako nabyo ni icyerekezo cy'ingenzi. Binyuze mu ikoranabuhanga rya microfabrication, miniaturization no guhuza bishobora kugerwaho kugira ngo hongerwe uburyo bwo kumva no gusubiza vuba.icyuma gipima foto. Mu guhuza ikoranabuhanga rigezweho ryo gutunganya ibimenyetso, igipimo cy'urusaku rw'ikimenyetso gishobora kongerwa, bigatuma gikomeza kubaho neza mu bidukikije bigoye. Si igikoresho cy'ingenzi cyo gupima amashusho, nk'igikoresho cy'ingenzi cyo gupima amashusho, kirimo guhindura ubuzima bwacu buhoro buhoro bitewe n'imikorere yacyo myiza n'ubushobozi bwacyo bwo gukoresha mu buryo bwagutse. Hamwe n'iterambere rihoraho ry'ikoranabuhanga, ibyuma bipima amashusho bishingiye kuri silicon bizagira uruhare runini mu nzego nyinshi, bizane amahirwe menshi mu gihe kizaza.
