Mu gihe cy'imikorere ya transistor, umuyoboro w'umwobo urakora, mu gihe urwego rw'amashanyarazi rugizwe n'icyiciro cy'amashanyarazi gikozwe mu buryo bwa cation
Abashakashatsi ba Kaminuza y'Igihugu ya Seoul bakoze transistor ikora urumuri rw'umwimerere rukoresha ingufu nke cyane, ishobora gukora isuzuma ry'ibimenyetso, kwibuka no kohereza urumuri icyarimwe mu gikoresho kimwe cya semiconductor. Mu gushyiramo icyuma gitera imbaraga iyoni mu muyoboro wa polymer semiconductor ukoresha urumuri, itsinda ryatumye habaho imiterere y'amashanyarazi n'ibice bibiri ku murongo wa electrode yo mu mazi, bituma habaho gutera electron neza hatabayeho kwishingikiriza ku ngufu nyinshi cyangwa gukoresha ikoranabuhanga ridasanzwe rya n-type doping rikoreshwa mu buryo busanzwe.
Kubera iyo mpamvu, igikoresho cyagumanye imiterere yoroshye y’urwego rumwe rw’imikorere, mu gihe cyageraga ku mikorere ya voltage nkeya ndetse no ku ikoreshwa ry’urumuri runini, hamwe n’imikorere yo gutunganya ibimenyetso bya neuromorphic.
Iki gikorwa cyasohotse mu kinyamakuru Nature Materials.
Ibikoresho by'ikoranabuhanga byambarwa birimo guhinduka vuba cyane uretse amasaha y'ubwenge n'indorerwamo zigezweho, bikaba byoroshye gukoresha mu gihe kizaza, ndetse no mu gihe kizaza bikajya mu bikoresho bikoreshwa ku ruhu no mu bikoresho bishobora gushyirwamo.
By’umwihariko, ibikoresho byambarwa ku ruhu, hamwe n’ikoranabuhanga rya semiconductor rihuriweho rihuza imikorere yo kumva, gutunganya ibimenyetso, kwibuka no kwerekana ibintu mu buryo bumwe, bifatwa nk’ikoranabuhanga ry’ingenzi rifasha mu buvuzi bw’ejo hazaza ndetse n’inganda z’ibikoresho by’ikoranabuhanga mu gihe kizaza.
Vuba aha, ibikoresho by'ikoranabuhanga byambarwa byateye imbere cyane kurusha uburyo bworoshye bwo kumenya ibimenyetso by'umubiri mu buryo bwo gutunganya no kwerekana ibimenyetso mu buryo bwihuse.
Ariko, kugeza ubu, iyi mirimo yakunze gushyirwa mu bikorwa hakoreshejwe ibikoresho bitandukanye bihujwe, bigatuma habaho imiterere igoye, ibice binini n'ibikomeye, ndetse n'ingufu nyinshi zikoreshwa. Kubwibyo, guhuza imirimo myinshi mu buryo bworoshye bw'ibikoresho byabaye imbogamizi ikomeye.
1. Impamvu ibikoresho bigezweho bigabanuka
Transistors zitanga urumuri rw’umwimerere zakunzwe cyane nk’abakandida beza ku bikoresho by’ikoranabuhanga byo mu gihe kizaza kuko zishobora guhuza imikorere ya transistors n’imikorere ya diode zitanga urumuri mu gikoresho kimwe.
Ariko, transistors zisanzwe za organic zifite imiterere ya electrode yo ku ruhande zikenera voltage nyinshi zikoreshwa kuva kuri 80 kugeza 180 V kubera intera ndende iri hagati ya electrodes n'urukuta runini ruterwa na electron.
Nubwo hakoreshejwe electrochemical ion doping kugira ngo igabanye voltage y'imikorere, haracyakenewe volti zirenga 3.5, kandi agace k'ibyuka bihumanya gakomeza kuba gato kandi kadahindagurika, bigatuma ikoreshwa ryabyo rigabanuka mu byuma bifatika n'ibikoresho by'ikoranabuhanga byambarwa neza.
2. Uburyo transistor nshya ikora
Itsinda ry’abashakashatsi ryakoze transistor ikora umucyo w’amashanyarazi ufite ingufu nke cyane, ihuza uburyo bwo gutunganya ibimenyetso, kwibuka no kohereza urumuri muri transistor imwe y’umwimerere.
Mu gushyiramo imashini itera imbaraga iyoni mu gice cy’imikorere kugira ngo itere imiterere y’amashanyarazi n’ibice bibiri ku murongo w’amashanyarazi, itsinda ryashyizeho uburyo bushya bwo gutera electroni neza hatabayeho kwishingikiriza ku muvuduko mwinshi cyangwa gukoresha doping idahindagurika ikoreshwa mu buryo busanzwe.
Ibi byatumye urumuri rusohora ndetse no ku muvuduko wa V uri munsi ya 3.5, mbere wafatwaga nk'aho uri hasi cyane ku buryo udashobora gukoreshwa, mu gihe bikomeza kugira agace kanini kandi gahamye k'ibyuka.
Iyi mashini kandi yagaragaje imiterere yo gutunganya ibimenyetso no kwibuka, aho ibisubizo byiyongeraga bitewe n’ibintu bikunze gukurura kandi bikaguma uko igihe kigenda gihita, kandi yanagaragajwe muri sisitemu yoroshye yo kwambara ikoresha bateri ebyiri za 1.5 V gusa.
Ubu bushakashatsi bwerekana ko urumuri rudahindagurika n'imikorere y'ubwenge bishobora kugerwaho icyarimwe ndetse no mu buryo bworoshye bwo gukora ku rwego rumwe, bikongera cyane ubushobozi bwa transistors z'umwimerere mu gukoreshwa mu buryo bwo kwambara.
3. Ingaruka zishobora kubaho ku myenda ikoreshwa mu kwambara
Ubu bushakashatsi ni ingenzi kuko buhuza uburyo bwo gutunganya ibimenyetso, kwibuka no kohereza urumuri mu gikoresho kimwe, bigabanya imbogamizi za sisitemu zisanzwe z'ikoranabuhanga zikenera ibice byinshi bitandukanye kugira ngo bikoreshwe kandi bihuzwe.
By’umwihariko, binyuze mu kugaragaza ibisubizo byimbitse kandi bihoraho ku bintu bikurura abantu, bigaragaza ubushobozi bw’ibikoresho by’ikoranabuhanga byo mu gihe kizaza bishobora gutunganya amakuru no kwerekana umusaruro ako kanya binyuze mu mucyo.
Mu gihe ibikoresho bisanzwe byo kwambarwa bitorohera abakoresha kugenzura ibimenyetso byapimwe mu gihe nyacyo mu gihe bagenda, iri koranabuhanga ryerekeza ku igenzura ry’igihe nyacyo no gutanga amakuru ako kanya.
Biteganijwe ko bizakoreshwa mu bikorwa nko gusana abarwayi, kwita ku barwayi mu gihe cy’impanuka, gukurikirana imyitozo ngororamubiri, ibikoresho by’ikoranabuhanga ku ruhu no kwita ku buzima bugezweho, kandi bishobora kuba ikoranabuhanga ry’ingenzi rifasha inganda zifitanye isano.
Porofeseri Tae-Woo Lee yagaragaje ubuhanga mu gupiganwa mu bushakashatsi ku isi binyuze mu bitabo bikurikirana byasohotse mu gitabo cya Siyansi n'Ibidukikije mu 2026.
Uyu murimo urenze ibikoresho bisanzwe bisohora urumuri binyuze mu gushyira mu bikorwa imikorere y’urumuri, gutunganya ibimenyetso n’imikorere y’ububiko mu gikoresho kimwe cya semiconductor kiri ku muvuduko muto, bitanga icyerekezo gishya cy’ibikoresho by’ikoranabuhanga byambarwa byo mu gihe kizaza.
Porofeseri Tae-Woo Lee, wayoboye ubu bushakashatsi, yagize ati: "Aya kazi afite akamaro cyane kuko agaragaza ko imikorere yose ishobora guhuzwa mu gikoresho kimwe cya semiconductor, hatabayeho gukora no guhuza ibice bitandukanye byo gutunganya, kwibuka, no kwerekana."
Yongeyeho ati: "Mu gihe kiri imbere, turateganya gukomeza guteza imbere iri koranabuhanga mu buryo bwa semiconductor ku ruhu, bukoreshwa ku ruhu rw'ubukorano n'ubuvuzi bw'abantu bambara."
Iri koranabuhanga kandi rifite akamaro kuko rirenze ibyuma bikoresha urumuri bisanzwe bigaragaza imikorere myinshi mu gikoresho kimwe cya semiconductor gifite voltage nkeya.
Muri ubu buryo, itanga icyerekezo gishya cy’ibikoresho by’ikoranabuhanga byambarwa ku ruhu bifasha abantu gukorana mu buryo bwihuse n’imashini.
