LiNbO3 Substrate
Ibisobanuro
LiNbO3 Crystal ifite ibikoresho bya electro-optique idasanzwe, piezoelectric, fotoelastic na optique optique.Biratandukanye cyane.Zikoreshwa muri laserfrequency gukuba kabiri, optique idafite umurongo, selile ya Pockels, oscillator ya optique, Q-guhinduranya ibikoresho bya laseri, izindi acousto-opticdevices, optique ya optique ya frequence ya gigahertz, nibindi. Nibikoresho byiza cyane byo gukora optique ya optique, nibindi.

Ibisobanuro bya LiNbO3:
LiNbO3 (lithium niobate) substrate bivuga ibintu bya kristaline ikunze gukoreshwa nka substrate cyangwa substrate mubikoresho bitandukanye bya elegitoroniki na optoelectronic.Hano hari ingingo zingenzi zerekeye LiNbO3 substrates:
1. Imiterere ya Crystal: LiNbO3 ni kristu ya ferroelektrike ifite imiterere ya perovskite.Igizwe na lithium (Li) na niobium (Nb) atom zitunganijwe muburyo bwihariye bwa kirisiti.
2. Imiterere ya Piezoelectric: LiNbO3 ifite imiterere ikomeye ya piezoelectric, bivuze ko itanga amashanyarazi mugihe ihuye nubukanishi nibindi.Uyu mutungo utuma bikwiranye nibisabwa nkibikoresho bya acoustic wave, sensor, actuators, nibindi.
3. Ibikoresho bifotora: LiNbO3 nayo ifite ibyiza bya optique na electro-optique.Ifite igipimo cyinshi cyo kwangirika, kwinjiza urumuri ruke, kandi ikerekana ibintu bizwi nkingaruka za electro-optique, aho indangagaciro zayo zishobora guhindurwa numuriro w'amashanyarazi wo hanze.Iyi mitungo ituma igira akamaro mubisabwa nka optique modulator, umurongo wogukoresha, inshuro ebyiri, nibindi byinshi.
4. Urwego runini rwo gukorera mu mucyo: LiNbO3 ifite uburyo bunini bwo gukorera mu mucyo, ikayemerera kohereza urumuri mu bigaragara kandi hafi-ya-infragre.Irashobora gukoreshwa muguhimba ibikoresho bya optique bikorera muri utwo turere twinshi.
5. Gukura kwa Crystal hamwe nicyerekezo: Kirisiti ya LiNbO3 irashobora guhingwa hakoreshejwe uburyo butandukanye nka Czochralski hamwe nuburyo bwo gukura bwimbuto zo hejuru.Irashobora gukatirwa no kwerekanwa muburyo butandukanye bwo kubona ibintu kugirango ubone ibikoresho bya optique n'amashanyarazi bikenewe muguhimba ibikoresho.
6. Ihungabana ryinshi ryimashini na chimique: LiNbO3 irahagaze neza muburyo bwa chimique na chimique, bituma ishobora kwihanganira
