I-LiTaO3 Substrate Definition
I-LiTaO3 (lithium tantalate) substrate ibhekisela ezintweni ezikristale ezivame ukusetshenziswa ezinhlelweni ezihlukahlukene ze-electronic kanye ne-optoelectronic.Nawa amanye amaphuzu abalulekile mayelana ne-LiTaO3 substrates:
1. Isakhiwo se-Crystal: I-LiTaO3 ine-perovskite crystal structure, ebonakala ngesakhiwo senethiwekhi esinezinhlangothi ezintathu zama-athomu oksijini lapho ama-athomu e-lithium ne-tantalum athatha izikhundla ezithile.
2. Izici ze-Piezoelectric: I-LiTaO3 i-piezoelectric ephezulu, okusho ukuthi ikhiqiza ukushaja kagesi uma ingaphansi kokucindezeleka kwemishini futhi ngokuphambene nalokho.Lesi sici sikwenza kube usizo kumadivayisi ahlukahlukene we-acoustic wave njengezihlungi ze-surface acoustic wave (SAW) namaresonators.
3. Izakhiwo ze-optical ezingezona umugqa: I-LiTaO3 ibonisa izici eziqinile ze-optical nonlinear, eziyenza ikwazi ukukhiqiza amafrikhwensi amasha noma iguqule izici zokukhanya kwesigameko ngokusebenzisa ukuxhumana okungaqondile.Ngokuvamile isetshenziswa kumadivayisi asebenzisa isizukulwane sesibili se-harmonic (SHG) noma i-optical parametric oscillation (OPO), njengamakristalu aphindwe kabili noma ama-optical modulators.
4. Uhlu olubanzi lokubonisa izinto obala: I-LiTaO3 inohlu olubanzi lokukhanyela kusuka ku-ultraviolet (UV) kuya esifundeni se-infrared (IR).Ingakwazi ukudlulisa ukukhanya kusuka cishe ku-0.38 μm kuya ku-5.5 μm, iyenze ifaneleke ezihlukahlukene zezinhlelo zokusebenza ze-optoelectronic ezisebenza kulolu hlu.
5. Izinga lokushisa eliphezulu le-Curie: I-LiTaO3 inezinga lokushisa eliphezulu le-Curie (Tc) elingaba ngu-610°C, okuyizinga lokushisa lapho izakhiwo zayo ze-piezoelectric kanye ne-ferroelectric zinyamalala khona.Lokhu kuyenza ifanelekele izicelo zokushisa okuphezulu okufana namadivayisi anamandla aphezulu we-acoustic wave noma izinzwa zokushisa okuphezulu.
6. Ukuzinza kwamakhemikhali: I-LiTaO3 izinzile kumakhemikhali futhi imelana nama-solvents nama-asidi avamile.Lokhu kuzinza kuqinisekisa ukuqina nokuthembeka kwe-substrate ezimeni ezihlukahlukene zokusebenza kanye nezindawo.
7. Izakhiwo ezinhle zemishini nezokushisa: I-LiTaO3 inamandla amahle omshini nokuzinza kokushisa, okuyenza ikwazi ukumelana nokucindezeleka komshini kanye nokushisa okuphezulu ngaphandle kokuguqulwa okuphawulekayo noma ukuwohloka.Lokhu kuyenza ilungele ukusetshenziswa kwamandla aphezulu noma izindawo ezinemishini enzima noma izimo ezishisayo.
Ama-substrates e-LiTaO3 asetshenziswa kabanzi ezinhlelweni ezihlukahlukene ezihlanganisa amadivaysi e-SAW, amadivaysi okuphindaphinda kabili kabili, ama-modulators optical, ama-waveguides optical, njll. izakhiwo ziyenza ibe yinto eguquguqukayo emkhakheni we-electronics kanye ne-optoelectronics.
