I-Superconductivity iyinto ebonakalayo lapho ukumelana kukagesi lapho ukumelana kagesi kwehla ku-zero endaweni yokushisa ethile ebucayi. I-Baddeen-Cooper-Schrieffer (BCS) theory iyincazelo ephumelelayo, echaza kakhulu izinto eziningi zokwakha. Kukhombisa ukuthi ama-cooper electron ngababili akhiwa ku-crystal lattice emazingeni okushisa aphansi ngokwanele, nokuthi ama-superconductivity we-BCS avela ekuvuseleleni kwawo. Yize i-Graphene ngokwayo ingumqhubi kagesi omuhle kakhulu, ayikhombisi ama-superconductivity we-BCS ngenxa yokuxinana kokuxhumana kwe-Electron-Phonon. Kungaleso sizathu "abalungile" abaningi "(njengegolide ne-Copper) yi-" mud "superconductors.
Abaphenyi enkabeni ye-theoretical physics yezinhlelo eziyinkimbinkimbi (ama-PC) esikhungweni sesayensi eyisisekelo (IBS, iSouth Korea) babike enye indlela entsha yokuthola i-supercoductivity. Bazuze lokhu ngokuhlongoza uhlelo lwe-hybrid oluhlanganiswe ne-graphene ne-bose-einstein condensate (BEC). Ucwaningo lushicilelwe kwiphephabhuku le-2D.
Uhlelo lwe-hybrid oluqukethe igesi ye-elektroni (ungqimba oluphezulu) ku-graphene, elihlukaniswe kusuka ku-condensal bose-einstein ezimbili-einstein, emelwe yizendlalelo ezingaqondile (eziluhlaza okwesibhakabhaka nezingqimba). Ama-elektroni kanye ne-expect in graphene ahlanganiswa yiCoulomm Force.
. . Umugqa wamachashazi aluhlaza okwesibhakabhaka ukhombisa izinga lokushisa le-BKT njengokusebenza kobuningi be-condensate.
Ngokungeziwe ku-Superconditivity, i-BEC ingenye into eyenzeka emazingeni okushisa aphansi. Yisimo sesihlanu sendaba eqale ebikezelwe ngu-Einstein ngo-1924. Ukwakheka kwe-BEC kwenzeka lapho ama-athomu aphansi-amandla ahlangana ndawonye futhi afake isimo esifanayo socwaningo, okuwumkhakha wocwaningo olunzulu e-confen udaba physics. Uhlelo lweHybrid Bose-Fermi empeleni lumelela ukusebenzisana kwe-elektroni ephethe ungqimba lwama-bosons, njengezinto ezingaqondile, ama-polarons, nokunye. Ukuxhumana phakathi kwe-BOSE ne-Fermi Izinhlayiya eziholele ezinhlotsheni ezahlukahlukene nezehlakalo ezihehayo, ezazivusa intshisekelo yazo zombili izinhlaka. Ukubuka okuyisisekelo nokususelwa kuhlelo lokusebenza.
Kulomsebenzi, abacwaningi babika indlela entsha ebabazekayo e-graphene, kungenxa yokusebenzisana phakathi kwama-elektroni kanye ne- "bogolons" kunokuba ama-pumples ohlelweni olujwayelekile lwe-BCS. Ama-Bogolons noma ama-bogoliubov quasiparticles amasehlakalo ku-BEC, anezici ezithile zezinhlayiya. Ngaphakathi kwamabanga athile wepharamitha, le ndlela ivumela ukushisa okubucayi okubucayi ku-graphene. Abaphenyi nabo bathuthukise umbono omusha we-Microscopic BCS ogxile kakhulu ezinhlelweni ezisuselwa ku-New Hybrid Graphene. Imodeli abayihlongoze futhi ibikezela nokuthi izakhiwo ezinhle kakhulu zingakhuphuka ngamazinga okushisa, okuholela ekuncikelweni kwezinga lokushisa okungewona ama-monotonic we-superconducting gap.
Ngaphezu kwalokho, ucwaningo selukhombisile ukuthi ukusakazwa kwe-dirac kwe-graphene kugcinwe kulolu hlelo olungaphakathi lwe-bogolon. Lokhu kukhombisa ukuthi le ndlela ye-superconducting ifaka ama-elektroni anokuhlakazeka okuhlobene, futhi le nto ayihlolisiswa kahle ku-folsics yendaba evunyelwe.
Lo msebenzi wembula enye indlela yokuthola amandla amakhulu okushisa. Ngasikhathi sinye, ngokulawula izakhiwo ze-condensate, singashintsha i-supercondivity ye-grapheene. Lokhu kukhombisa enye indlela yokulawula amadivaysi aphezulu ngokuzayo.
