LiTaO3 Ma'anar Substrate
LiTaO3 (lithium tantalate) substrate yana nufin wani abu na crystalline da aka saba amfani dashi a aikace-aikacen lantarki daban-daban da na optoelectronic.Anan akwai wasu mahimman mahimman bayanai game da kayan aikin LiTaO3:
1. Crystal Tsarin: LiTaO3 yana da tsarin lu'ulu'u na perovskite, wanda aka kwatanta da tsarin cibiyar sadarwa mai girma uku na kwayoyin oxygen a cikin abin da lithium da tantalum atom suka mamaye matsayi na musamman.
2. Piezoelectric Properties: LiTaO3 yana da piezoelectric sosai, wanda ke nufin yana haifar da cajin wutar lantarki lokacin da aka fuskanci damuwa na inji kuma akasin haka.Wannan fasalin yana sa ya zama mai amfani a cikin na'urori masu sauti daban-daban kamar masu tacewa (SAW) da kuma resonators.
3. Kayayyakin gani na gani mara kyau: LiTaO3 yana nuna ƙaƙƙarfan kaddarorin na gani mara kyau, yana ba shi damar samar da sabbin mitoci ko canza halayen hasken abin da ya faru ta hanyar hulɗar da ba ta dace ba.Yawancin lokaci ana amfani da shi a cikin na'urori masu amfani da ƙarni na biyu masu jituwa (SHG) ko oscillation na gani na gani (OPO), kamar mitar lu'ulu'u biyu ko na'urori masu daidaita gani.
4. Faɗin fa'ida: LiTaO3 yana da fa'ida mai fa'ida daga ultraviolet (UV) zuwa yankin infrared (IR).Yana iya watsa haske daga kusan 0.38 μm zuwa 5.5 μm, yana sa ya dace da aikace-aikacen optoelectronic iri-iri masu aiki a cikin wannan kewayon.
5. High Curie zafin jiki: LiTaO3 yana da babban Curie zafin jiki (Tc) game da 610 ° C, wanda shi ne zazzabi a inda ta piezoelectric da ferroelectric Properties bace.Wannan ya sa ya dace da aikace-aikacen zafin jiki mai girma kamar na'urorin raƙuman sauti mai ƙarfi ko na'urori masu auna zafin jiki.
6. Chemical kwanciyar hankali: LiTaO3 sinadari barga da kuma juriya ga mafi na kowa kaushi da acid.Wannan kwanciyar hankali yana tabbatar da dorewa da amincin ma'aunin a cikin yanayi daban-daban da yanayin aiki.
7. Kyakkyawan kayan aikin injiniya da kayan zafi: LiTaO3 yana da kyakkyawan ƙarfin injiniya da kwanciyar hankali na thermal, yana ba shi damar yin tsayayya da damuwa na inji da kuma yawan zafin jiki ba tare da raguwa ko raguwa ba.Wannan ya sa ya dace da manyan aikace-aikacen wuta ko mahalli tare da matsananciyar inji ko yanayin zafi.
LiTaO3 substrates ana amfani da ko'ina a cikin aikace-aikace daban-daban ciki har da na'urorin SAW, mita biyu na na'urori, na'urori masu daidaitawa, masu amfani da wutar lantarki, da dai sauransu. Haɗin sa na piezoelectric da maras kyau na gani na gani, fadi da kewayon nuna gaskiya, high Curie zafin jiki, sinadarai kwanciyar hankali, kuma mai kyau inji da thermal. Kaddarorin sun sa ya zama kayan aiki iri-iri a fagen lantarki da optoelectronics.
