SrTiO3 Ma'anar Substrate
SrTiO3 substrate yana nufin wani sinadari na crystalline da aka yi daga fili na strontium titanate (SrTiO3).SrTiO3 wani abu ne na perovskite tare da tsarin kristal mai siffar sukari, wanda ke da alaƙa da babban dielectric akai-akai, babban kwanciyar hankali na thermal, da kyakkyawan lattice daidai da sauran kayan.
SrTiO3 substrates ana amfani da ko'ina a cikin filayen na bakin ciki saka fim da epitaxial girma.Tsarin mai siffar sukari na SrTiO3 yana ba da damar haɓaka manyan fina-finai na bakin ciki masu inganci tare da ingantaccen ingancin crystalline da ƙarancin lahani.Wannan ya sa SrTiO3 substrates ya dace sosai don haɓaka fina-finai na epitaxial da tsarin heterostructures don aikace-aikace daban-daban.
Babban dielectric akai-akai na SrTiO3 yana sa ya dace da aikace-aikace kamar capacitors, na'urorin ƙwaƙwalwar ajiya, da fina-finai na bakin ciki na ferroelectric.Tsawon yanayin zafi ya sa ya dace da aikace-aikacen zafin jiki mai girma.
Bugu da ƙari kuma, nau'ikan kaddarorin SrTiO3, kamar ƙarfin ƙarfin sa na ƙarfe a ƙananan yanayin zafi da yuwuwar haifar da yanayi mai ƙarfi, suna sa ya zama mai amfani ga binciken ilimin kimiyyar lissafi da ƙima da haɓaka na'urorin lantarki da na'urorin gani.
A taƙaice, SrTiO3 substrates su ne crystalline substrates sanya daga strontium titanate, wanda aka saba amfani a cikin bakin ciki jita-jita fim, epitaxial girma, da kuma fadi da kewayon lantarki da optoelectronic aikace-aikace saboda su high dielectric akai, thermal kwanciyar hankali, da kuma kyau lattice matching Properties.
