Ma'anar Substrate na LiNbO3:
LiNbO3 (lithium niobate) substrate yana nufin wani abu mai kristal da aka saba amfani da shi azaman maɓalli ko ƙasa a cikin na'urorin lantarki daban-daban da na optoelectronic.Anan akwai wasu mahimman mahimman bayanai game da kayan aikin LiNbO3:
1. Crystal tsarin: LiNbO3 ne ferroelectric crystal tare da perovskite tsarin.Ya ƙunshi lithium (Li) da kuma niobium (Nb) atom waɗanda aka shirya cikin ƙayyadaddun lattice na crystal.
2. Piezoelectric Properties: LiNbO3 yana da karfi piezoelectric Properties, wanda ke nufin yana haifar da cajin lantarki lokacin da aka fuskanci damuwa na inji kuma akasin haka.Wannan kadarar ta sa ta dace da aikace-aikace kamar na'urorin raƙuman sauti, firikwensin, masu kunnawa, da sauransu.
3. Photoelectric Properties: LiNbO3 kuma yana da kyau kwarai na gani da kuma electro-optic Properties.Yana da babban maƙasudin refractive, ƙananan ƙarancin haske, kuma yana nuna wani abu da aka sani da tasirin lantarki, inda za'a iya canza ma'anar refractive ta filin lantarki na waje.Waɗannan kaddarorin suna sa ya zama mai amfani a aikace-aikace kamar na'urorin daidaitawa na gani, jagororin raƙuman ruwa, masu ninka mita, da ƙari.
4. Faɗin fa'ida: LiNbO3 yana da fa'ida mai fa'ida, yana ba shi damar watsa haske a bayyane da kuma kusa da bakan infrared.Ana iya amfani da shi don ƙirƙira na'urorin gani waɗanda ke aiki a cikin waɗannan yankuna masu tsayi.
5. Crystal girma da fuskantarwa: LiNbO3 lu'ulu'u za a iya girma ta amfani da hanyoyi daban-daban kamar Czochralski da saman-seeded bayani girma dabaru.Ana iya yanke shi da daidaitawa cikin kwatance daban-daban don samun takamaiman kayan gani da lantarki da ake buƙata don ƙirƙira na'urar.
6. Babban injina da kwanciyar hankali: LiNbO3 yana da ƙarfi da ƙarfi da ƙarfi, yana ba shi damar jurewa.
