Superconductivity shine sabon abu na zahiri wanda juriya da tsayayya da kayan maye a wasu zafin jiki mai mahimmanci. Ka'idar-Cooper-Cooper-Schrieffer (bcs) ra'ayi ne mai amfani, wanda ke bayyana Supercontity a cikin yawancin kayan. Yana nuna cewa an kafa nau'ikan nau'ikan kayan lantarki a cikin ƙarancin zafin jiki, kuma cewa BCS SuperConetarre ya fito daga Cikin Cikin Ciki. Kodayake graphene kanta kyakkyawan kyakkyawan jagorar lantarki, ba ta nuna BCS Supercontity saboda ɗaukar ma'amala ta lantarki ba. This is why most “good” conductors (such as gold and copper) are “bad” superconductors.
Masu bincike a Cibiyar Kula da Likitocin Kayayyaki (PCs) a Cibiyar Kimiyya (Ibs, Koriya ta Kudu) ta ruwaito wata sabuwar hanyar samar da tsari a Superatived.

Baya ga Superconductivity, bec wani sabon abu ne wanda ke faruwa a yanayin zafi. Yana da labarin na biyar da Einstein ya annabta ta hanyar 1924. Samuwar Biyu ya faru yayin da Tumfa mai ƙarfi, wanda shine filin bincike mai zurfi a cikin ilimin kimiyyar lissafi. Tsarin matasan-Fermi da gaske yana wakiltar hulɗa na Layer na lantarki tare da Layer na Bosons, kamar kuɗaɗen kai tsaye, watsun-polarons, da sauransu.

A cikin wannan aikin, masu binciken sun ba da rahoton sabon tsarin aiki a cikin Graphete, wanda yake saboda hulɗa tsakanin wayoyin lantarki da "Bogolons" maimakon phonons a cikin tsarin BCS na hali. Bogolons ko Bogoliubov Quasiparticles a cikin Bec, wanda ke da wasu halaye na barbashi. A cikin wasu siga na sigari, wannan tsarin yana ba da damar haɓaka zafin jiki mai mahimmanci a cikin Graphene don isa zuwa 70 Kelvin. Masu binciken sun kuma inganta sabon ka'idar BCS na BCS wanda musamman ya mai da hankali kan tsarin dangane da sabon graphen sabon grongne.

Bugu da kari, nazarin sun nuna cewa Dirac Diske an kiyaye shi a cikin wannan tsarin da ake kira na Bogolon. Wannan yana nuna cewa wannan tsarin sarrafawa ya ƙunshi wayoyin lantarki tare da watsarwar bayanan ta sake, kuma wannan ba a bincika wannan sabon abu ba cikin ilimin kimiyyar lissafi.
Wannan aikin ya bayyana wata hanyar da za ta cimma nasarar samar da zazzabi. A lokaci guda, ta hanyar sarrafa kaddarorin condensate, zamu iya daidaita da superconcontity na graphene. Wannan ya nuna wata hanya don magance na'urori masu haɓaka a nan gaba.
