LiNbO3 Substrate Inkcazo:
I-LiNbO3 (i-lithium niobate) i-substrate ibhekiselele kwi-crystalline material edla ngokusetyenziswa njenge-substrate okanye i-substrate kwizixhobo ezahlukeneyo zombane kunye ne-optoelectronic.Nanga amanye amanqaku aphambili malunga ne-LiNbO3 substrates:
1. Isakhiwo se-Crystal: I-LiNbO3 yikristale ye-ferroelectric enesakhiwo se-perovskite.Iqukethe i-lithium (Li) kunye ne-niobium (Nb) ii-athomu ezihlelwe kwi-crystal lattice ethile.
2. Iimpawu ze-Piezoelectric: I-LiNbO3 ineempawu ezinamandla ze-piezoelectric, oku kuthetha ukuba ivelisa iindleko zombane xa iphantsi koxinzelelo lomatshini kunye nokunye.Le propati iyenza ilungele izicelo ezifana nezixhobo zamaza e-acoustic, izinzwa, ii-activators, njl.
3. Iimpawu ze-Photoelectric: I-LiNbO3 nayo ineempawu ezintle kakhulu ze-optical kunye ne-electro-optic.Inesalathisi esiphezulu se-refractive index, ukukhanya okuphantsi kokukhanya, kwaye kubonisa into eyaziwa ngokuba yi-electro-optic effect, apho isalathisi sayo sokuhlaziya singatshintshwa yintsimi yangaphandle yombane.Ezi zakhiwo ziyenza ibe luncedo kwizicelo ezinjengeemodyuli zokukhanya, ii-waveguides, ii-frequency doubles, kunye nokunye.
4. Uluhlu olubanzi lokungafihli: I-LiNbO3 inoluhlu olubanzi lwe-transparency, evumela ukuba idlulisele ukukhanya kwi-spectrum ebonakalayo kunye ne-infrared spectrum.Ingasetyenziselwa ukwenza izixhobo ze-optical ezisebenza kule mimandla yobude bamaza.
5. Ukukhula kweCrystal kunye nokuqhelaniswa: Iikristali ze-LiNbO3 zinokukhuliswa kusetyenziswa iindlela ezahlukeneyo ezifana neCzochralski kunye neendlela zokukhula kwesisombululo se-top-seeded.Inokunqunyulwa kwaye iqondiswe kwiindlela ezahlukeneyo zekristallographic ukufumana iipropathi ezithile zokukhanya kunye nombane ezifunekayo ukwenza isixhobo.
6. Uzinzo oluphezulu lomatshini kunye neekhemikhali: I-LiNbO3 izinzile ngoomatshini kunye neekhemikhali, eyenza ukuba imelane.
