I loko o nā mea superconducting, e kahe ana kahi au uila me ke kū ʻole.He kakaikahi wale no ka hoohana ana i keia ano;akā naʻe, nui nā nīnau kumu i koe ʻaʻole i pane ʻia.Ua aʻo ʻo Polofesa Justin Ye, ke poʻo o ka hui Device Physics of Complex Materials ma ke Kulanui o Groningen, i ka superconductivity i kahi papa pālua o ka molybdenum disulfide a ua ʻike i nā mokuʻāina superconducting hou.Ua paʻi ʻia nā hopena ma ka puke pai Nature Nanotechnology ma 4 Nowemapa.

Ua hōʻike ʻia ka superconductivity i loko o nā kristal monolayer o, no ka laʻana, molybdenum disulphide a i ʻole tungsten disulfide i loaʻa ka mānoanoa o ʻekolu mau ʻātoma wale nō."I loko o nā monolayers ʻelua, aia kahi ʻano superconductivity kūikawā kahi e pale ai ke kahua magnetic kūloko i ke kūlana superconducting mai nā māla magnetic waho," wehewehe ʻo Ye.Nalo ka superconductivity maʻamau i ka wā e hoʻohana ʻia ai kahi māla magnetic waho nui, akā pale ikaika kēia Ising superconductivity.ʻOiai i loko o ke kahua magnetic static ikaika loa ma ʻEulopa, nona ka ikaika o 37 Tesla, ʻaʻole hōʻike ka superconductivity i ka tungsten disulfide i kahi loli.Eia nō naʻe, ʻoiai he mea maikaʻi loa ka loaʻa ʻana o ia ʻano pale ikaika, ʻo ka luʻi hou e ʻimi i kahi ala e hoʻomalu ai i kēia hopena pale, ma ka hoʻohana ʻana i kahi kahua uila.

Nā mokuʻāina superconducting hou

Ua aʻo ʻo ʻoe a me kāna mau hoa hana i kahi papa pālua o ka molybdenum disulfide: "Ma kēlā hoʻonohonoho, hana ka pilina ma waena o nā papa ʻelua i nā mokuʻāina superconducting hou."Ua hana ʻoe i kahi papa ʻelua i hoʻokuʻu ʻia, me kahi wai ionic ma nā ʻaoʻao ʻelua i hiki ke hoʻohana ʻia e hana i ke kahua uila ma waena o ka bilayer."Ma ka monolayer hoʻokahi, e like ʻole kēlā kahua, me nā ion maikaʻi ma kekahi ʻaoʻao a me nā hoʻopiʻi maikaʻi ʻole i hoʻokomo ʻia ma kekahi ʻaoʻao.Eia nō naʻe, i ka bilayer, hiki iā mākou ke loaʻa ka nui o ka uku i hoʻokomo ʻia i nā monolayers ʻelua, e hana ana i kahi ʻōnaehana symmetrical, "wehewehe ʻo Ye.Hiki ke hoʻohana ʻia ke kahua uila i hana ʻia e hoʻololi i ka superconductivity a i ʻole.ʻO ke ʻano kēia, ua hana ʻia kahi transistor superconducting i hiki ke hoʻopaʻa ʻia ma o ka wai ionic.

Ma ka papa ʻelua, nalo ka pale Ising i nā māla magnetic waho."Hiki kēia ma muli o nā loli i ka pilina ma waena o nā papa ʻelua."Eia naʻe, hiki i ke kahua uila ke hoʻihoʻi i ka pale."ʻO ke kiʻekiʻe o ka pale e lilo i mea hana no ka ikaika o kou puka ʻana i ka hāmeʻa."

Cooper pai

Ma waho aʻe o ka hana ʻana i kahi transistor superconducting, ua hana ʻo Ye a me kāna mau hoa hana i kahi ʻike hoihoi.I ka makahiki 1964, ua wānana ʻia kahi mokuʻāina superconducting kūikawā, i kapa ʻia ʻo FFLO state (i kapa ʻia ma hope o nā ʻepekema nāna i wānana: Fulde, Ferrell, Larkin a me Ovchinnikov).I ka superconductivity, hele pālua nā electrons ma nā ʻaoʻao ʻē aʻe.Ma muli o ko lākou holo like ʻana, loaʻa i kēia mau hui Cooper ka huina kinetic momentum o ka ʻole.Akā ma ka moku'āina FFLO, aia kahi ʻokoʻa wikiwiki a no laila ʻaʻole ʻaʻole ʻole ka manawa kinetic.I kēia manawa, ʻaʻole i aʻo pono ʻia kēia mokuʻāina i nā hoʻokolohua.

"Ua hālāwai mākou i nā mea e pono ai no ka hoʻomākaukau ʻana i ka mokuʻāina FFLO i kā mākou hāmeʻa," wahi a Ye."Akā ua palupalu loa ka moku'āina a ua hoʻopilikia nui ʻia e nā mea ʻino ma luna o kā mākou mea.No laila, pono mākou e hana hou i nā hoʻokolohua me nā mea hoʻomaʻemaʻe maʻemaʻe. "

Me ka bilayer hoʻokuʻu ʻia o ka molybdenum disulfide, loaʻa iā ʻoe a me nā hoa hana nā mea āpau e pono ai ke aʻo ʻana i kekahi mau mokuʻāina superconducting kūikawā."He ʻepekema kumu maoli kēia e lawe mai iā mākou i nā loli manaʻo."
