MgO substrate
wehewehe
Hiki ke hoʻohana ʻia ka substrate hoʻokahi MgO e hana i nā lako kamaʻilio kelepona i koi ʻia no nā kānana microwave superconducting kiʻekiʻe a me nā mea hana ʻē aʻe.
Ua hoʻohana mākou i kahi hoʻoliʻiliʻi kemika i hiki ke hoʻomākaukau ʻia no kahi pae atomika kiʻekiʻe o ka ʻili o ka huahana, ʻo ka substrate nui loa 2"x 2"x0.5mm i loaʻa.

ʻO ka MgO, pōkole no ka magnesium oxide, he substrate aniani hoʻokahi i hoʻohana mau ʻia ma ke kahua o ka waiho ʻana o ke kiʻiʻoniʻoni lahilahi a me ka ulu epitaxial.Loaʻa iā ia kahi ʻano aniani cubic a me ka maikaʻi kristal maikaʻi loa, e kūpono ana ia no ka ulu ʻana i nā kiʻiʻoniʻoni lahilahi kiʻekiʻe.
ʻIke ʻia nā substrate MgO no ko lākou mau ʻili laulima, kūpaʻa kemika kiʻekiʻe, a me ka haʻahaʻa haʻahaʻa haʻahaʻa.Hoʻolilo kēia mau waiwai iā lākou i mea kūpono no nā noi e like me nā mea semiconductor, media recording magnetic, a me nā mea optoelectronic.
I ka waiho ʻia ʻana o nā kiʻiʻoniʻoni lahilahi, hāʻawi nā substrates MgO i nā laʻana no ka ulu ʻana o nā mea like ʻole me nā metala, semiconductor a me nā oxides.Hiki ke koho pono ʻia ke ʻano aniani o ka substrate MgO e hoʻohālikelike i ke kiʻiʻoniʻoni epitaxial i makemake ʻia, e hōʻoia ana i kahi kiʻekiʻe o ka alignment kristal a me ka hōʻemi ʻana i ka lattice mismatch.
Eia kekahi, hoʻohana ʻia nā substrates MgO i ka media hoʻopaʻa leo magnetic ma muli o ko lākou hiki ke hāʻawi i kahi ʻano kristal i kauoha ʻia.ʻO kēia ka mea e hiki ai ke hoʻopololei maikaʻi ʻia o nā kāʻei kapu magnetic i loko o ka mea hoʻopaʻa hoʻopaʻa leo, e hopena i ka maikaʻi o ka mālama ʻana i ka ʻikepili.
I ka hopena, ʻo MgO hoʻokahi substrates he kiʻekiʻe kiʻekiʻe crystalline substrates i hoʻohana ʻia ma ke ʻano he kumu hoʻohālike no ka ulu ʻana o ka epitaxial o nā kiʻiʻoniʻoni lahilahi i nā noi like ʻole, me nā semiconductors, optoelectronics, a me ka media recording magnetic.
