SrTiO3 Pāpā
wehewehe
ʻO SrTiO3 ke aniani hoʻokahi he ʻano lattice maikaʻi o nā mea hana perovskite.He mea substrate maikaʻi loa ia no ka ulu epitaxy o HTS a me ka hapa nui o nā kiʻiʻoniʻoni oxide.Ua hoʻohana nui ʻia i ka noiʻi ʻana i nā kiʻi ʻoniʻoni lahilahi superconducting wela.Hoʻohana nui ʻia ia i nā puka aniani kūikawā a me nā pahuhopu sputtering kiʻekiʻe.

SrTiO3 Kahua wehewehe
ʻO ka pāpaʻi SrTiO3 e pili ana i kahi pani aniani i hana ʻia me ka strontium titanate hui (SrTiO3).ʻO SrTiO3 kahi mea perovskite me kahi ʻano aniani cubic, kahi i hōʻike ʻia e ke kiʻekiʻe dielectric mau, kiʻekiʻe thermal stability, a me ka lattice maikaʻi e pili ana me nā mea ʻē aʻe he nui.
Hoʻohana nui ʻia nā substrates SrTiO3 i nā kahua o ka deposition kiʻiʻoniʻoni lahilahi a me ka ulu epitaxial.ʻO ka hana cubic o SrTiO3 hiki ke ulu i nā kiʻiʻoniʻoni lahilahi kiʻekiʻe me ka maikaʻi crystalline maikaʻi a me ka haʻahaʻa haʻahaʻa haʻahaʻa.ʻO kēia ka mea kūpono loa i nā substrates SrTiO3 no ka ulu ʻana i nā kiʻiʻoniʻoni epitaxial a me nā heterostructures no nā noi like ʻole.
ʻO ke kiʻekiʻe dielectric mau o SrTiO3 kūpono ia no nā noi e like me nā capacitors, nā mea hoʻomanaʻo, a me nā kiʻiʻoniʻoni lahilahi ferroelectric.ʻO kona kūpaʻa wela e kūpono ia no nā noi wela kiʻekiʻe.
Eia kekahi, ʻo nā waiwai like ʻole o SrTiO3, e like me kona conductivity metala ma nā haʻahaʻa haʻahaʻa a me ka hiki ke hoʻoulu i kahi kūlana superconducting, he mea pono ia no ka noiʻi physics condensed a me ka hoʻomohala ʻana i nā mea uila a me optoelectronic.
I ka hōʻuluʻulu manaʻo, SrTiO3 substrates he crystalline substrates i hana ʻia me ka strontium titanate, ka mea maʻamau i hoʻohana ʻia i ka deposition kiʻiʻoniʻoni lahilahi, ulu epitaxial, a me ka nui o nā noi uila a me optoelectronic ma muli o ko lākou kiʻekiʻe dielectric mau, thermal stability, a me nā waiwai hoʻohālikelike maikaʻi.
