LiTaO3 Substrate
Ibisobanuro
LiTaO3 kristu imwe ifite amashanyarazi meza cyane, piezoelectric na pyroelectric, kandi ikoreshwa cyane mubikoresho bya pyroelectric na TV yamabara.

LiTaO3 Ibisobanuro Byibisobanuro
LiTaO3 (lithium tantalate) substrate bivuga ibikoresho bya kristaline ikunze gukoreshwa muburyo butandukanye bwa elegitoroniki na optoelectronic.Hano hari ingingo zingenzi zerekeye LiTaO3 substrates:
1. Imiterere ya Crystal: LiTaO3 ifite imiterere ya kirisiti ya perovskite, irangwa nuburyo butatu bwurusobe rwimiterere ya atome ya ogisijeni aho atome ya lithium na tantalum ifata imyanya yihariye.
2. Imiterere ya Piezoelectric: LiTaO3 ni piezoelectric cyane, bivuze ko itanga amashanyarazi mugihe ihuye nikibazo cya mashini nibindi.Iyi mikorere ituma igira akamaro mubikoresho bitandukanye bya acoustique nkubuso bwa acoustic wave (SAW) muyunguruzi na resonator.
3. Ibikoresho bya optique bidafite umurongo: LiTaO3 yerekana ibintu byiza bidafite umurongo wa optique, bikabasha kubyara imirongo mishya cyangwa guhindura ibiranga urumuri rwibyabaye binyuze mumikoranire idafite umurongo.Ubusanzwe ikoreshwa mubikoresho bikoresha igisekuru cya kabiri gihuza (SHG) cyangwa optique ya parametric oscillation (OPO), nka kristu yikubye kabiri cyangwa moderi nziza.
4. Inzira nini yo gukorera mu mucyo: LiTaO3 ifite umucyo mwinshi kuva ultraviolet (UV) kugeza mukarere ka infragre (IR).Irashobora kohereza urumuri kuva kuri 0.38 mkm kugeza kuri 5.5 mm, bigatuma rukwiranye na porogaramu zitandukanye za optoelectronic zikoreshwa muriki cyiciro.
5. Ubushyuhe bwo hejuru bwa Curie: LiTaO3 ifite ubushyuhe bwinshi bwa Curie (Tc) bugera kuri 610 ° C, nubushyuhe ubushyuhe bwa piezoelectric na ferroelectric bubura.Ibi bituma bikwiranye nubushyuhe bwo hejuru nkububasha bwo hejuru bwa acoustic wave ibikoresho cyangwa sensor yubushyuhe bwo hejuru.
6. Ihungabana ryimiti: LiTaO3 ihagaze neza kandi irwanya imiti myinshi na acide.Uku gushikama kwemeza kuramba no kwizerwa kwa substrate mubikorwa bitandukanye no mubidukikije.
7. Ibikoresho byiza bya mashini nubushyuhe: LiTaO3 ifite imbaraga zumukanishi hamwe nubushyuhe bwumuriro, bikabasha kwihanganira imihangayiko nubushyuhe bwo hejuru nta guhindagurika cyangwa kwangirika gukomeye.Ibi bituma bikwiranye nimbaraga nyinshi zikoreshwa cyangwa ibidukikije hamwe nubukanishi bukabije cyangwa ubushyuhe.
LiTaO3 substrates ikoreshwa cyane mubikorwa bitandukanye birimo ibikoresho bya SAW, ibikoresho byikubye kabiri, modulatrice optique, optique yumurongo wa optique, nibindi. imitungo ikora ibintu byinshi muburyo bwa electronics na optoelectronics.
