BaTiO3 Ma'anar Substrate
BaTiO3 substrate yana nufin wani sinadari na crystalline da aka yi daga fili barium titanate (BaTiO3).BaTiO3 abu ne na ferroelectric tare da tsarin lu'ulu'u na perovskite, wanda ke nufin yana da kaddarorin lantarki na musamman, yana sa ya dace da aikace-aikace iri-iri.
BaTiO3 sau da yawa ana amfani da substrates a fagen sirara fina-finai, kuma ana amfani da su musamman don girma epitaxial bakin ciki fina-finai na daban-daban kayan.Tsarin crystalline na substrate yana ba da damar daidaitaccen tsari na atoms, yana ba da damar haɓakar manyan fina-finai na bakin ciki masu inganci tare da kyawawan kaddarorin crystallographic.Abubuwan ferroelectric na BaTiO3 suma suna taka muhimmiyar rawa a aikace-aikace kamar na'urorin lantarki da na'urorin ƙwaƙwalwar ajiya.Yana nuna polarization na kwatsam da ikon canzawa tsakanin jihohin polarization daban-daban a ƙarƙashin tasirin filin waje.
Ana amfani da wannan kadarorin a cikin fasaha kamar ƙwaƙwalwar ajiya mara ƙarfi (ƙwaƙwalwar ferroelectric) da na'urorin gani na lantarki.Bugu da kari, BaTiO3 substrates suna da aikace-aikace a fagage daban-daban kamar na'urorin piezoelectric, na'urori masu auna firikwensin, masu kunnawa, da abubuwan microwave.Kayan lantarki na musamman na BaTiO3 yana ba da gudummawa ga aikinsa, yana sa ya dace da waɗannan aikace-aikacen.
