Mu bintu bifite ubuhanga bwo hejuru nka optoelectronics, ikoranabuhanga ryo kwerekana, n'ibikoresho by'urumuri, ijambo "optical thin film" rikunze kugaragara. Ibi bipfuka bigira ingaruka ku buryo butaziguye ku bipimo by'ingenzi by'imikorere nko kohereza, gusubiza urumuri, no kwerekana amabara, kandi amaherezo bigahindura ubunararibonye bw'ishusho n'umusaruro w'umusaruro wa nyuma. Ariko se koko filime zoroheje z'urumuri ni iki, kandi ni gute zigeraho mu buryo bunoze bwo guhindura urumuri binyuze mu ikoranabuhanga rigezweho ryo gushushanya? Iyi nkuru itanga incamake y'ikoranabuhanga.
Filimi zo mu bwoko bwa Optical Thin ni iki?
Filimi ntoya zikoresha urumuri zivuga ku bikoresho bikora neza bifite ubugari kuva kuri nanometero kugeza kuri mikorometero, akenshi bishyirwa ku kirahure, pulasitiki, cyangwa substrates z'icyuma hakoreshejwe ikoranabuhanga ryo gusiga irangi ry'umwuka nko gushyuha, gukoresha magnetron, cyangwa gushyiramo electron beam. Izi filime zishobora kuba zigizwe n'urwego rumwe cyangwa urwego rwinshi rugizwe, buri rumwe rufite ibipimo bitandukanye byo kugarura ubushyuhe n'ubunini, byakozwe kugira ngo bigere ku ngaruka zihariye z'urumuri.
Amahame y'ibanze: Kwivanga no Gusubira inyuma
Uburyo bw'ingenzi inyuma ya filime ntoya z'urumuri ni ukwivanga kw'urumuri. Iyo urumuri ruhuye n'ubuso bwa filime ntoya, rugaragara igice kandi rugasubirwamo kuri buri gice. Bitewe n'ubugari bwa filime bugenzurwa n'ibipimo bitandukanye byo kwigaragaza hagati y'ibice, imirasire yagaragaye ishobora kwivanga mu buryo bw'ubwubatsi cyangwa mu buryo bwangiza, bitewe n'itandukaniro ryabyo mu cyiciro.
Urugero:
Iyo ubugari bwa firime bukozwe ku buryo imiraba igaragara ihuza, ingaruka zo kudasubiza urumuri ziraboneka—zikunze gukoreshwa mu mboni cyangwa mu kirahuri gitwikiriye urumuri rw'izuba.
Ku rundi ruhande, iyo imiraba igaragara iri mu cyiciro, irakomezanya, bigatuma habaho kuyungurura cyane cyangwa gutoranya uburebure bw'umuraba—nk'uko bigaragara mu bikoresho bigabanya imirasire, indorerwamo za laser, cyangwa mu byuma biyungurura urumuri.
Ubu buryo bwo guhindura uburebure bw'inzira y'urumuri buri mu mutima w'igishushanyo mbonera cya thin-film, aho ubunini busanzwe ari kimwe cya kane cy'uburebure bw'umurambararo (λ/4) cyangwa inshuro nyinshi zabwo, bigatuma habaho kugenzura neza imirongo yihariye ya spectral.
Ubwoko busanzwe bw'amabara akoreshwa mu gusiga irangi
Imyambaro Idahindura Umucyo (AR Coatings): Igabanya urumuri rw'inyuma kandi yongere ubushobozi bwo kohereza. Ikoreshwa cyane ku nyubako z'indorerwamo z'amaso, kamera, n'ibikoresho byo gukoraho.
Imyambaro Igaragaza Umucyo Ukabije (HR Coatings): Yongera urumuri ku mirasire y'uburebure, ikoreshwa mu ndorerwamo za laser, amatara yo ku rubyiniro, na optique igezweho.
Imyambaro yo gushungura urumuri: Ihitamo kohereza cyangwa guhagarika uburebure bw'uburebure bwihariye. Iboneka mu byuma bipima urumuri, ibikoresho by'urumuri, n'ibikoresho by'itumanaho.
Filimi zigabanya urumuri rw'umurambararo/zigabanya urumuri: Gutandukanya urumuri hakurikijwe imiterere y'uburebure bw'urumuri cyangwa imiterere y'urumuri, rukoreshwa mu byuma bipima urumuri, porojekiteri, n'ibigaragaza urumuri rw'imodoka (HUDs).
Igishushanyo n'Ubuhanga bwa Filimi Zito z'Ikoranabuhanga
Filimi ntoya zikora neza cyane zisaba guhitamo neza ibikoresho gusa, ahubwo zisaba no gushushanya neza urwego rw'ibyiciro no kugenzura uburyo ibintu bikorwamo. Ikoranabuhanga rigezweho ryo gushyiramo ibikoresho ririmo:
Guhinduka kw'ubushyuhe
Guhinduka kw'umuraba wa Electron Beam (E-Beam)
Kunyunyuza Magnetron
Gutanga Ion-Assisted Deposition (IAD)
Ubu buryo bwemerera ubunini bwa nanometero gukora neza kandi bugatuma habaho imiterere imwe y'urumuri ku bice binini by'ubutaka.
Mu by’ukuri, filime ntoya zikora binyuze mu guhindura uburyo urumuri rukwirakwira binyuze mu kubangamira, bigatuma habaho kongera ubushobozi bwo kugabanya, kuyungurura cyangwa kugenzura imiterere y’urumuri. Izi mashini zihuza ikoranabuhanga rigezweho, ubumenyi bw’ibikoresho, no gushyira mu buryo bunoze ibyuma bitanga urumuri mu ikoranabuhanga rimwe, bigira uruhare runini mu nganda zigezweho zikora fotonike n’izikora ku rwego rwo hejuru. Uko umubare w’ibikoresho bitanga urumuri ukora neza cyane, bidatakaza byinshi, kandi bito, udushya dukomeje mu ikoranabuhanga rikoresha fotonike ntoya tuzakomeza gutera imbere mu nganda.
