Munguva yekushanda kwetransistor, mugero wegomba unoumbwa, ukuwo jira remagetsi rine cation rakaita serakaviri
Vaongorori veSeoul National University vakagadzira transistor yemagetsi ine simba rakaderera remagetsi inogona kuita panguva imwe chete kugadzirisa masaini, kurangarira uye kuburitsa chiedza mukati memudziyo mumwe chete we semiconductor. Nekuisa ion-transport enhancer muchiteshi chepolymer semiconductor chinoburitsa chiedza, timu iyi yakagonesa kugadzirwa kwemagetsi maviri-maviri-layer panzvimbo ye drain electrode interface, zvichibvumira kupinza maerekitironi zvakanaka pasina kuvimba nemagetsi akakwira kana kusagadzikana kwen-type doping inoshandiswa munzira dzemazuva ese.
Nekuda kweizvozvo, mudziyo uyu wakachengetedza chimiro chiri nyore che single-active-layer ukuwo uchishanda nesimba uye nekuparara kwechiedza, pamwe chete ne neuromorphic signal-processing functionality.
Basa iri rakaburitswa mumagazini inonzi Nature Materials.
Magetsi emagetsi anopfekwa ari kuchinja nekukurumidza kupfuura mawachi emazuva ano nemagirazi akangwara kuita mapuratifomu echizvarwa chinotevera ari nyore kushandisa, nekuwedzera kuri kuitwa kune zvishandiso zvinopfekwa paganda uye zvinopfekwa paganda.
Zvikuru sei, zvishandiso zvinopfekwa paganda, pamwe chete nematekinoroji e semiconductor akabatanidzwa anosanganisa kunzwa, kugadzirisa masaini, kurangarira uye mabasa ekuratidzira pachikuva chimwe chete, anoonekwa sematekinoroji akakosha ekuchengetedza hutano hwechizvarwa chinotevera uye indasitiri yemagetsi yeramangwana.
Munguva pfupi yapfuura, zvigadzirwa zvemagetsi zvinopfekwa zvafambira mberi kupfuura kungoona zviratidzo zvemuviri zviri nyore kusvika pakugadzirisa zviratidzo nenguva chaiyo uye kuona.
Zvisinei, kusvika pari zvino, mabasa aya anowanzoitwa achishandisa michina yakasiyana yakabatana, zvichikonzera maumbirwo akaomarara, zvikamu zvakakura uye zvakaoma, uye kushandiswa kwesimba rakawanda. Saka, kubatanidza mabasa akawanda mukati mekugadzirwa kwemidziyo kuri nyore kwave dambudziko guru.
1. Nei zvishandiso zviripo zvino zvikasashanda zvakanaka
Matransistors anoburitsa chiedza echisikigo akwezva vanhu sevanoda kushandisa magetsi echizvarwa chinotevera nekuti anogona kusanganisa mabasa etransistor nelight-emitting diode mumudziyo mumwe chete.
Zvisinei, ma transistors echinyakare eorganic ane chimiro che lateral electrode anoda ma voltages ekushanda akakwira e80 kusvika 180 V nekuda kwedaro refu pakati pema electrodes nechinhu chikuru chinopinzwa ma electron.
Kunyangwe kana electrochemical ion doping ichishandiswa kudzikisa voltage yekushanda, inodiwa kupfuura 3.5 V, uye nzvimbo yekuburitsa inoramba yakamanikana uye isina kugadzikana, zvichideredza kushandiswa kwayo muzviratidziro chaizvo uye masisitimu emagetsi anopfekwa zvine hungwaru.
2. Mashandiro anoita transistor itsva
Chikwata chekutsvagisa chakagadzira transistor ine simba rakaderera remagetsi emagetsi emakemikari emuchadenga inobatanidza kugadzirwa kwemasaini, kurangarira uye kuburitswa kwechiedza mukati me transistor imwe chete yemuchadenga.
Nekuisa ion-transport enhancer mu active layer kuti iite electric-double-layer formation panzvimbo ye electrode interface, timu iyi yakaunza nzira itsva yekuisa ma electron injection zvakanaka pasina kuvimba ne high voltages kana kusagadzikana kwe doping kunoshandiswa munzira dzemazuva ese.
Izvi zvakaita kuti chiedza chibudiswe kunyange pamagetsi ari pasi pe3.5 V, ayo aimboonekwa seakaderera zvakanyanya kuti ashande, ukuwo achichengetedza nzvimbo yakafara uye yakagadzikana yekubuditswa kwechiedza.
Mudziyo uyu wakaratidzawo hunhu hwekugadzirisa masaini uye hwekurangarira, nemhinduro dzichiungana pasi pekukurudzira kunodzokororwa uye dzichichengetwa nekufamba kwenguva, uye wakaratidzwa zvakare musystem yekuratidza inopfekwa inochinjika ine mabhatiri maviri e1.5 V chete.
Chidzidzo ichi chinoratidza kuti kuburitswa kwechiedza kwakasimba uye kushanda kwakangwara zvinogona kuwanikwa panguva imwe chete kunyangwe muchimiro chakareruka che single-active-layer, zvichiwedzera zvakanyanya kugona kwema organic transistors ekushandisa anogona kupfekwa.
3. Kukanganisa kunogona kuitika pazvipfeko zvinopfekwa
Chidzidzo ichi chakakosha nekuti chinobatanidza kugadzirwa kwemasaini, ndangariro uye kuburitswa kwechiedza mumudziyo mumwe chete, zvichideredza miganhu yemasisitimu emagetsi anopfekwa echinyakare anoda kuti zvikamu zvakasiyana-siyana zvigadzirwe uye zvibatanidzwe.
Zvikuru, nekuratidzawo mhinduro dzinounganidzwa uye dzinoramba dzichienderera mberi kune zvinokurudzira, zvinoratidza kugona kwemagetsi echizvarwa chinotevera anogona kugadzirisa ruzivo uye kuratidza mhedzisiro yacho nekukurumidza kuburikidza nechiedza.
Kunyange zvazvo michina yemazuva ano inopfekwa ichiita kuti zviomere vashandisi kutarisa zviratidzo zvakayerwa panguva chaiyo pavanenge vachifamba, tekinoroji iyi inonongedzera kukutarisa panguva chaiyo uye kutumirwa kwemashoko nekukurumidza.
Inotarisirwa kuwedzerwa kune zvishandiso zvakaita sekugadzirisa, kutarisira varwere panguva yekukurumidza, kutarisa maekisesaizi, midziyo yemagetsi inogadzirwa paganda uye hutano hwakanaka, uye inogona kushanda se tekinoroji inobatsira maindasitiri ane hukama.
Purofesa Tae-Woo Lee akaratidza kukwikwidzana kwekutsvaga ruzivo pasi rose kuburikidza nemabhuku akatevedzana muScience and Nature muna 2026.
Basa iri rinodarika zvishandiso zvemazuva ano zvinoburitsa chiedza nekubatanidza magetsi anoburitsa chiedza, kugadzirisa masaini uye mashandiro ekurangarira mumudziyo mumwe chete we semiconductor pamagetsi akaderera, zvichipa gwara idzva remagetsi echinyakare akangwara anogona kupfekwa.
Purofesa Tae-Woo Lee, uyo akatungamira chidzidzo ichi, akati, "Basa iri rine zvarinoreva zvakanyanya nekuti rinoratidza kuti mabasa ese anogona kubatanidzwa mukati memudziyo mumwe chete we semiconductor, pasina chikonzero chekugadzira nekubatanidza zvikamu zvekugadzirisa, zvekurangarira, uye zvekuratidza zvakasiyana."
Akawedzera kuti, "Tichiri kuenderera mberi, tinoronga kuwedzera kuvandudza tekinoroji iyi kuita puratifomu ye semiconductor inogadzirwa paganda inoshanda kune ganda rekugadzira rakangwara uye hutano hunopfekwa."
Tekinoroji iyi inokoshawo nekuti inopfuura ma semiconductors emazuva ano anoburitsa chiedza nekuratidza mashandiro akawanda mumudziyo mumwe chete une voltage shoma.
Mupfungwa iyi, inopa gwara idzva remagetsi akangwara anopfekwa paganda ayo anogonesa kutaurirana panguva chaiyo pakati pevanhu nemichina.
