Ka thepa ea superconducting, motlakase o tla phalla ntle le khanyetso leha e le efe.Ho na le lisebelisoa tse 'maloa tse sebetsang tsa ketsahalo ena;leha ho le joalo, lipotso tse ngata tsa bohlokoa li ntse li e-s’o arajoe.Motlatsi oa Moprofesa Justin Ye, hlooho ea sehlopha sa The Device Physics of Complex Materials Univesithing ea Groningen, o ile a ithuta superconductivity sebakeng se habeli sa molybdenum disulfide mme a fumana linaha tse ncha tsa superconducting.Liphetho li phatlalalitsoe koranteng ea Nature Nanotechnology ka la 4 Pulungoana.

Superconductivity e bontšitsoe ka likristale tsa monolayer, mohlala, molybdenum disulphide kapa tungsten disulfide tse nang le botenya ba liathomo tse tharo feela."Ka bobeli ba li-monolayers, ho na le mofuta o khethehileng oa superconductivity oo matla a khoheli a ka hare a sireletsang boemo ba superconducting ho tloha ka ntle ho matla a khoheli," E oa hlalosa.Superconductivity e tloaelehileng ea nyamela ha ho sebelisoa matla a maholo a khoheli a kantle, empa superconductivity ena ea Ising e sirelelitsoe ka matla.Esita le sebakeng se matla ka ho fetisisa sa matla a khoheli Europe, se nang le matla a 37 Tesla, superconductivity ka tungsten disulfide ha e bontše phetoho leha e le efe.Leha ho le joalo, le hoja ho le monate ho ba le tšireletso e matla joalo, phephetso e latelang ke ho fumana mokhoa oa ho laola phello ena ea tšireletso, ka ho sebelisa sebaka sa motlakase.

Linaha tse ncha tsa superconducting

Ye le basebetsi-'moho le eena ba ithutile karolo e 'meli ea molybdenum disulfide: "Tlhahisong eo, tšebelisano lipakeng tsa mekhahlelo e' meli e theha linaha tse ncha tsa superconducting."Le thehile lera le emisitsoeng le habeli, le nang le mokelikeli oa ionic mahlakoreng ka bobeli a ka sebelisoang ho theha lebala la motlakase ka mose ho bilayer."Ho motho ka mong, sebaka se joalo se tla ba sa asymmetric, se nang le li-ion tse ntle ka lehlakoreng le leng le liqoso tse mpe tse hlahisoang ka lehlakoreng le leng.Leha ho le joalo, ka bilayer, re ka ba le tefiso e ts'oanang e kentsoeng ho li-monolayers ka bobeli, ho theha tsamaiso ea symmetrical, "Ye oa hlalosa.Sebaka sa motlakase se entsoeng ka tsela eo se ka sebelisoa ho fetola superconductivity le ho tima.Sena se bolela hore ho entsoe transistor ea superconducting e neng e ka kengoa ka mokelikeli oa ionic.

Karolong e 'meli, tšireletso ea Ising khahlanong le matla a khoheli a kantle e nyamela."Sena se etsahala ka lebaka la liphetoho tšebelisanong lipakeng tsa mekhahlelo e 'meli."Leha ho le joalo, sebaka sa motlakase se ka tsosolosa tšireletso."Boemo ba ts'ireletso bo fetoha ts'ebetso ea hore na o kenya sesebelisoa ka matla hakae."

Lipara tsa Cooper

Ntle le ho theha transistor ea superconducting, Ye le basebetsi-'moho le eena ba ile ba etsa tlhokomeliso e 'ngoe e makatsang.Ka 1964, ho ile ha boleloa esale pele hore boemo bo khethehileng ba superconducting bo tla ba teng, bo bitsoang naha ea FFLO (e reheletsoeng ka bo-rasaense ba ileng ba e bolela esale pele: Fulde, Ferrell, Larkin le Ovchinnikov).Ka superconductivity, lielektrone li tsamaea ka bobeli ka mahlakoreng a fapaneng.Kaha li tsamaea ka lebelo le tšoanang, lipara tsena tsa Cooper li na le lebelo la kinetic la zero.Empa seterekeng sa FFLO, ho na le phapang e nyane ea lebelo mme ka hona lebelo la kinetic ha se zero.Ho fihlela joale, naha ena ha e e-s'o ithutoe hantle litekong.

"Re fihletse litlhokahalo tsohle tsa ho lokisa boemo ba FFLO sesebelisoa sa rona," ho bolela Ye."Empa mmuso o fokola haholo mme o angoa haholo ke tšilafalo e holim'a thepa ea rona.Ka hona, re tla hloka ho pheta liteko ka lisampole tse hloekileng. ”

Ka bilayer e emisitsoeng ea molybdenum disulfide, Ye le basebetsi ba na le lisebelisoa tsohle tse hlokahalang ho ithuta linaha tse ling tse khethehileng tsa superconducting."Ena ke saense ea bohlokoa e le kannete e ka re tlisetsang liphetoho tsa maikutlo."
