Fa'auigaga o le Substrate BaTiO3
BaTiO3 substrate e faasino i se mea tioata tioata e faia i le barium titanate (BaTiO3).BaTiO3 o se mea ferroelectric ma se fausaga tioata perovskite, o lona uiga o loʻo i ai mea faʻapitoa eletise, faʻapitoa mo le tele o talosaga.
O substrates BaTiO3 e masani ona faʻaaogaina i le fanua o le faʻapipiʻiina o ata manifinifi, ma faʻapitoa e faʻaaogaina e tupu ai ata manifinifi epitaxial o mea eseese.O le fausaga tioata o le substrate e mafai ai ona faʻatulagaina saʻo o atoms, e mafai ai ona tupu aʻe ata manifinifi maualuga ma mea sili ona lelei tioata.O meatotino ferroelectric a BaTiO3 o loʻo iai foʻi se sao taua i faʻaoga e pei o mea tau eletise ma masini manatua.O loʻo faʻaalia ai le polarization faʻafuaseʻi ma le mafai ona fesuiaʻi i le va o setete polarization eseese i lalo o le faatosinaga a se fanua i fafo.
O lenei meatotino o loʻo faʻaaogaina i tekinolosi e pei ole manatua e le faʻafefe (ferroelectric memory) ma masini eletise.E le gata i lea, o le BaTiO3 substrates o loʻo i ai talosaga i vaega eseese e pei o masini piezoelectric, sensors, actuators, ma vaega microwave.O mea tau eletise ma masini faʻapitoa o le BaTiO3 e saofagā i lona faʻatinoga, e talafeagai ai mo nei talosaga.
