wehewehe
ʻO ka aniani hoʻokahi o ka dysprosium scandium acid he lattice kūpono maikaʻi me ka superconductor o Perovskite (kūkulu).

ʻO ka wehewehe ʻana o DyScO3 substrate
ʻO ka substrate DyScO3 (dysprosium scandate) e pili ana i kahi ʻano mea pani i hoʻohana mau ʻia ma ke kahua o ka ulu kiʻiʻoniʻoni lahilahi a me ka epitaxy.ʻO ia kahi substrate kristal hoʻokahi me kahi ʻano aniani kikoʻī i haku ʻia me ka dysprosium, scandium a me nā ion oxygen.
Loaʻa i nā substrates DyScO3 kekahi mau waiwai i makemake ʻia e kūpono iā lākou no nā noi like ʻole.Aia kēia mau mea me nā helu heheʻe kiʻekiʻe, ka paʻa wela maikaʻi, a me ka lattice mismatch me nā mea oxide he nui, e hiki ai i ka ulu ʻana o nā kiʻiʻoniʻoni lahilahi epitaxial kiʻekiʻe.
He kūpono kēia mau substrate no ka hoʻoulu ʻana i nā kiʻiʻoniʻoni lahilahi oxide paʻakikī me nā waiwai i makemake ʻia, e like me ka ferroelectric, ferromagnetic a i ʻole nā mea superconducting kiʻekiʻe.ʻO ka lattice mismatch ma waena o ka substrate a me ke kiʻiʻoniʻoni e hoʻoulu i ke kāʻei kiʻiʻoniʻoni, nāna e hoʻomalu a hoʻonui i kekahi mau waiwai.
Hoʻohana mau ʻia nā substrates DyScO3 i nā hale hana R&D a me nā wahi ʻoihana e ulu i nā kiʻiʻoniʻoni lahilahi e nā ʻenehana e like me ka pulsed laser deposition (PLD) a i ʻole molecular beam epitaxy (MBE).Hiki ke hana hou ʻia nā kiʻiʻoniʻoni i loaʻa a hoʻohana ʻia i nā ʻano o nā noi, e like me ka uila, ka ʻohi ikehu, nā mea ʻike a me nā mea photonic.
I ka hōʻuluʻulu ʻana, ʻo ka substrate DyScO3 he substrate aniani hoʻokahi i haku ʻia me nā ion dysprosium, scandium a me ka oxygen.Hoʻohana ʻia lākou e ulu i nā kiʻiʻoniʻoni lahilahi kiʻekiʻe me nā waiwai i makemake ʻia a loaʻa i nā noi ma nā ʻano like ʻole e like me ka uila, ikehu a me ka optics.
