Nkọwa mkpụrụ okwu SrTiO3
Mkpụrụ SrTiO3 na-ezo aka na mkpụrụ osisi kristal emere site na strontium titanate (SrTiO3).SrTiO3 bụ a perovskite ihe na a cubic crystal Ọdịdị, nke e ji a elu dielectric mgbe nile, elu thermal kwụsie ike, na ezi lattice kenha na ọtụtụ ihe ndị ọzọ.
A na-eji ihe ndị SrTiO3 eme ihe n'ọtụtụ ebe n'ọhịa nke ntinye ihe nkiri dị mkpa na uto epitaxial.The cubic Ọdịdị nke SrTiO3 na-enye ohere uto nke elu-edu mkpa fim na magburu onwe crystalline àgwà na ala ntụpọ njupụta.Nke a na-eme ka SrTiO3 substrates dabara adaba maka ihe nkiri epitaxial na-eto eto na heterostructures maka ngwa dị iche iche.
Igwe dielectric dị elu nke SrTiO3 na-eme ka ọ dabara maka ngwa dị ka capacitors, ngwaọrụ ebe nchekwa na ihe nkiri ferroelectric dị mkpa.Nkwụsi ike ya na-ekpo ọkụ na-eme ka ọ dị mma maka ngwa okpomọkụ dị elu.
Ọzọkwa, ihe dị iche iche nke SrTiO3, dị ka ya dara conductivity na ala okpomọkụ na ohere nke inducing a superconducting ala, na-eme ka ọ bara uru maka condensed okwu physics nnyocha na mmepe nke electronic na optoelectronic ngwaọrụ.
Na nchịkọta, SrTiO3 substrates bụ kristal substrates nke strontium titanate, nke a na-ejikarị eme ihe na ntinye ihe nkiri dị mkpa, uto epitaxial, na ọtụtụ ngwa eletrọnịkị na ngwa optoelectronic n'ihi na ha dị elu dielectric na-adịgide adịgide, nkwụsi ike okpomọkụ, na ezigbo lattice dakọtara Njirimara.
