Substrate-ka LiNbO3
Sharaxaada
LiNbO3 Crystal waxay leedahay koronto-optical, piezoelectric, photoelastic iyo sifooyin indho-indhayn oo gaar ah.Aad bay u kala fog yihiin.Waxaa loo isticmaalaa in laserfrequency double, optics aan online ahayn, Pockels unugyo, oscillators parametric indhaha, Q-beddelka qalabka lasers, qalab kale oo acousto-optics, furaha indhaha ee frequencies gigahertz, iwm.

Qeexitaan Substrate-ka LiNbO3:
Substrate LiNbO3 (lithium niobate) waxa loola jeedaa walxo crystalline ah oo caadi ahaan loo isticmaalo substrate ama substrate ee aaladaha kala duwan ee elegtarooniga iyo indhaha.Waa kuwan qaar ka mid ah qodobbada muhiimka ah ee ku saabsan substrate-ka LiNbO3:
1. Qaab dhismeedka Crystal: LiNbO3 waa crystal ferroelectric leh qaab-dhismeedka perovskite.Waxay ka kooban tahay lithium (Li) iyo niobium (Nb) atamka oo lagu habeeyay shabag crystal gaar ah.
2. Qalabka Piezoelectric: LiNbO3 waxay leedahay sifooyin piezoelectric xoog leh, taas oo macnaheedu yahay in ay soo saarto kharashyada korantada marka ay la kulmaan cadaadis farsamo iyo lid ku ah.Gurigan wuxuu ka dhigayaa mid ku habboon codsiyada sida aaladaha hirarka dhawaaqa, dareemayaasha, kiciyayaasha, iwm.
3. Qalabka sawir-qaadista: LiNbO3 waxa kale oo uu leeyahay sifooyin indho-indheyn iyo koronto-optic aad u fiican.Waxay leedahay index refractive sare, nuugista iftiinka hooseeya, waxayna muujisaa ifafaale loo yaqaan saamaynta elektro-optic, halkaas oo tusmaheeda refractive lagu beddeli karo goob koronto oo dibadda ah.Guryahaani waxay ka dhigaan mid faa'iido u leh codsiyada sida modulators indhaha, waveguides, soo noqnoqda labajibbaaran, iyo in ka badan.
4. Daah-furnaan ballaaran: LiNbO3 waxay leedahay daah-furnaan ballaaran, taas oo u oggolaanaysa inay u gudbiso iftiinka muuqaalka muuqda iyo kuwa u dhow-infrared spectrum.Waxaa loo isticmaali karaa in lagu sameeyo aaladaha indhaha ee ka shaqeeya gobolladan hirarka dhaadheer.
5. Kobaca Crystal iyo hanuuninta: Kiristaalo LiNbO3 waxaa lagu kori karaa iyadoo la isticmaalayo habab kala duwan sida Czochralski iyo farsamooyinka koritaanka sare-seeded.Waa la gooyn karaa oo lagu jihayn karaa jihooyin crystallographic kala duwan si loo helo sifooyinka indhaha iyo korantada gaarka ah ee looga baahan yahay qalabaynta.
6. Degganaanshiyaha farsamada iyo kiimikaad sare: LiNbO3 si farsamaysan iyo kiimiko ahaan waa u xasiloon tahay, taas oo awood u siinaysa inay u adkaysato
