wehewehe
(La, Sr) (Al, Ta) O 3 he kristal perovskite ole-crystalline i hoʻohālikelike maikaʻi ʻia me nā superconductors kiʻekiʻe a me nā ʻano mea oxide.Ua manaʻo ʻia e hoʻololi ʻia ka lanthanum aluminate (LaAlO 3) a me ka strontium titanate (SrO 3) i nā magnetoelectrics nunui a me nā mea hana superconducting i kahi helu nui o nā noi kūpono.

ʻO LaAlO3 ka wehewehe ʻana o ka substrate
ʻO LaAlO3 substrate e pili ana i kahi mea kikoʻī i hoʻohana ʻia ma ke ʻano he substrate a i ʻole ke kumu i nā noi ʻepekema a me ka ʻenehana no ka ulu ʻana i nā kiʻiʻoniʻoni lahilahi o nā mea like ʻole.Loaʻa ia i ke ʻano crystalline o ka lanthanum aluminate (LaAlO3), ka mea maʻamau i hoʻohana ʻia ma ke kahua o ka waiho ʻana o nā kiʻiʻoniʻoni lahilahi.
Loaʻa i nā substrates LaAlO3 nā waiwai i makemake ʻia no ka ulu ʻana i nā kiʻiʻoniʻoni lahilahi, e like me ko lākou ʻano crystalline kiʻekiʻe, kūpono ʻole ka lattice maikaʻi me nā mea ʻē aʻe he nui, a me ka hiki ke hāʻawi i kahi ili kūpono no ka ulu epitaxial.
ʻO ka Epitaxial ke kaʻina hana o ka hoʻoulu ʻana i kahi kiʻiʻoniʻoni lahilahi ma luna o kahi substrate kahi e hoʻohālikelike ai nā ʻātoma o ka kiʻiʻoniʻoni me nā mea o ka substrate e hana i kahi ʻano i kauoha ʻia.
Hoʻohana nui ʻia nā substrate LaAlO3 i nā kula e like me ka electronics, optoelectronics, a me ka solid-state physics, kahi e koʻikoʻi ai nā kiʻi ʻoniʻoni ʻoniʻoni no nā polokalamu like ʻole.ʻO kāna mau waiwai kūʻokoʻa a me ka hoʻohālikelike ʻana me nā mea like ʻole he mea nui ia no ka noiʻi a me ka hoʻomohala ʻana i kēia mau kahua.
ʻO ka wehewehe ʻana o nā Superconductors kiʻekiʻe
ʻO nā superconductors kiʻekiʻe (HTS) nā mea e hōʻike ana i ka superconductivity i nā wela kiʻekiʻe i hoʻohālikelike ʻia me nā superconductors maʻamau.Pono nā superconductors maʻamau i nā wela haʻahaʻa loa, ma lalo o -200°C (-328°F), e hōʻike i ka pale uila ʻole.ʻO ka hoʻohālikelike, hiki i nā mea HTS ke hoʻokō i ka superconductivity i nā mahana e like me -135°C (-211°F) a ma luna.
