DyScO3 Nkọwa Substrate
DyScO3 (dysprosium scandate) mkpụrụ akụ na-ezo aka n'ụdị mkpụrụ ihe a na-ejikarị eme ihe n'ubi nke ihe nkiri dị mkpa na epitaxy.Ọ bụ otu mkpụrụ kristal nwere ụdị kristal akọwapụtara nke mejupụtara dysprosium, scandium na ion oxygen.
Ngwa DyScO3 nwere ọtụtụ ihe a na-achọsi ike na-eme ka ha dabara maka ngwa dị iche iche.Ndị a na-agụnye ebe mgbaze dị elu, ezigbo nkwụsi ike nke okpomọkụ, na lattice na-adaba na ọtụtụ ihe oxide, na-enyere aka itolite ihe nkiri epitaxial dị elu.
Ihe ndị a dabara adaba maka ihe nkiri oxide dị mgbagwoju anya nwere ihe ndị a chọrọ, dị ka ferroelectric, ferromagnetic ma ọ bụ ihe na-ekpo ọkụ dị elu.Esemokwu nke lattice n'etiti mkpụrụ na ihe nkiri na-ebute nsogbu ihe nkiri, nke na-achịkwa ma na-akwalite ụfọdụ akụrụngwa.
