BaTiO3 Substrate Definition

I-substrate ye-BaTiO3 ibhekisa kwi-crystalline substrate eyenziwe nge-compound barium titanate (BaTiO3).I-BaTiO3 yimpahla ye-ferroelectric ene-perovskite crystal structure, oku kuthetha ukuba ineempawu ezikhethekileyo zombane, okwenza kube yinto efanelekileyo kwizicelo ezahlukeneyo.

Ii-substrates ze-BaTiO3 zihlala zisetyenziswa kwintsimi ye-deposition yefilimu encinci, kwaye isetyenziselwa ngokukodwa ukukhulisa iifilimu ezincinci ze-epitaxial zezinto ezahlukeneyo.Ubume bekristale be-substrate buvumela ukucwangciswa okuchanekileyo kwee-athomu, okwenza ukuba kukhule iifilimu ezikumgangatho ophezulu ezibhityileyo ezineempawu ezibalaseleyo zecrystallographic.Iipropati ze-ferroelectric ze-BaTiO3 zikwadlala indima ebalulekileyo kwii-aplikeshini ezifana ne-electronics kunye nezixhobo zememori.Ibonisa i-polarization ezenzekelayo kunye nokukwazi ukutshintsha phakathi kwamazwe ahlukeneyo e-polarization phantsi kweempembelelo zentsimi yangaphandle.

Le propati isetyenziswe kwiiteknoloji ezifana nememori engaguqukiyo (imemori ye-ferroelectric) kunye nezixhobo ze-electro-optical.Ukongeza, ii-substrates ze-BaTiO3 zinezicelo kwiinkalo ezahlukeneyo ezifana nezixhobo ze-piezoelectric, izinzwa, ii-actuator, kunye namacandelo e-microwave.Iimpawu ezizodwa zombane kunye nezomatshini ze-BaTiO3 zinegalelo ekusebenzeni kwayo, okwenza ukuba ilungele ezi zicelo.
