SupercondComring ndi chodabwitsa chathupi momwe kukana magetsi kwa zinthu kumatsikira kwa zero pamtunda wina wovuta kwambiri. Chiphunzitso cha bardeen-cooper-schrieffer (BCS) ndi malongosoledwe oyenera, omwe amafotokoza za supercondection mu zinthu zambiri. Zimalongosola kuti awiri eleorron amapangidwa mu kristali yotentha kwambiri kutentha kokwanira, ndipo kuti ma BCS SuperCouring amachokera ku kuvomerezedwa kwawo. Ngakhale munthu amagetsi omwewo ndi ochititsa opanga zamagetsi, sizikuwonetsa BCS SuperConsCotriving chifukwa cha zokambirana za kulumikizana kwa ma elenon. Ichi ndichifukwa chake "chabwino" (monga golide ndi mkuwa) ndi "zoyipa" supercondoctors.
Ofufuzawo pakati pa zisudzo zamakina ovuta (ma PC) ku Institute of Science (Ibs, South Korea) adanenanso njira yatsopano kuti mukwaniritse ziwengo. Anakwaniritsa izi polosera kachitidwe ka hybrid yopangidwa ndi graphene ndi mitsempha iwiri ya BOSE-Einstein Chermensin (Bec). Kafukufukuyu anafalitsidwa mu magazini 2D.

Dongosolo la hybrid lokhala ndi mpweya wa electron (pamwamba pamtunda) ku graphene, olekanitsidwa ndi magawo awiri a Bose-Einstein Chemeninsate, kuyimitsidwa ndi zigawo zosawoneka bwino (zigawo zabuluu ndi zofiira). Ma elekitironi ndi zopindika mu graphene amaphatikizidwa ndi mphamvu ya Comlomb.

. . Mzere wa buluu wokhala ndi Blue amawonetsa kutentha kwa BKT ngati ntchito yopanga kachulukidwe.

Kuphatikiza pa superconduction, bec ndi izi zina zomwe zimachitika pamatenthedwe ochepa. Ndi gawo lachisanu la zinthu zomwe zinanenedweratu ndi Einstein mu 1924. Kupanga kwa Bec kumachitika pomwe ma atomu otsika kwambiri amasonkhana ndikulowetsa mphamvu yofananira, yomwe ndi gawo la kafukufuku wa zinthu zolimbikitsira. The hybrid Bydiyo ya Fermid imayimira kulumikizana kwa ma elekitoni a ma elekinons okhala ndi ma boson, monga othandizira osalunjika, opitira-opindika, ndi zina zambiri. Kuyanjana pakati pa a BOSE ndi michere kumadzetsa zatsopano komanso zodabwitsa, zomwe zidadzutsa chidwi cha maphwando onse. Mawonekedwe oyambira komanso ogwiritsira ntchito.
Mu ntchitoyi, ofufuzawo adanenanso zamakina atsopano ku graphene, zomwe zimachitika chifukwa cha kulumikizana pakati pa ma elekitoni ndi "ma bololoni" osati ma a phonon mu dongosolo la BCS. Bololons kapena bogolibov quasarys ndi zokondweretsa mu bec, zomwe zili ndi mawonekedwe ena a tinthu. M'magawo ena m'mizere ina, makinawa amalola kutentha kovuta kovuta ku graphene kuti ifikire kwambiri 70 kellvin. Ofufuzawo apanganso chiphunzitso chatsopano cha BCS chomwe chimayang'ana kwambiri pamakina ozikidwa pa graphene yatsopano ya hybrid. Zoyimira zomwe akuganiza zimaloseranso kuti katundu wa zinthu zapamwamba amatha kuwonjezeka ndi kutentha, zomwe zimapangitsa kutentha komwe sikudalira kuwongolera kwapamwamba kwa kapaso.
Kuphatikiza apo, maphunziro awonetsa kuti dikirani diaction wobayira graphene amasungidwa mu chiwembu chomwe chamezedwa ndi Bololon. Izi zikuwonetsa kuti njira yopambana iyi imaphatikizapo ma elekitironi ophatikizika, ndipo izi sizinatengeke bwino m'magazini a zinthu zodandaula.
Ntchitoyi imavumbula njira ina yopezera ndalama zotentha kwambiri. Nthawi yomweyo, poyendetsa zinthu zomwe zimapangitsa kuti tisinthe, titha kusintha zopambana za graphene. Izi zikuwonetsanso njira ina yowongolera zida zapamwamba mtsogolo.
