3 inji 4 inji 6 inji LiNbO3 Wafer Substrate Walax keli ah oo kiristaalo ah
Macluumaad Faahfaahsan
Kiristaalo Lithium niobate ah waxay leeyihiin sifooyin electro-optic, acoustooptic, piezoelectric iyo nonlinear ah oo aad u fiican. Kiristaalo Lithium niobate ah waa kiristaalo badan oo muhiim ah oo leh sifooyin aragti oo aan toosnayn oo wanaagsan iyo isku-xidhnaan aragti oo aan toosnayn oo weyn. Intaa waxaa dheer, isku-xidhka wejiga aan muhiimka ahayn waa la xaqiijin karaa. Sida kiristaalo elektaroonik ah, waxaa loo isticmaalay sidii walxo muhiim ah oo hagaha mowjadaha indhaha. Sida kiristaalo piezoelectric ah, waxaa loo isticmaali karaa soo saarista shaandheeyayaasha SAW ee soo noqnoqda oo hooseeya, transducers-ka ultrasonic-ka ee heerkulka sare u adkaysta iyo wixii la mid ah. Agabka lithium niobate ee la duray ayaa sidoo kale si weyn loo isticmaalaa. Mg:LN si weyn ayuu u hagaajin karaa heerka dhaawaca ka hortagga laysarka, wuxuuna kor u qaadi karaa isticmaalka kiristaalo lithium niobate ah oo ku jira goobta indhaha aan tooska ahayn. Kiristaalo Nd:Mg:LN ah, waxay gaari kartaa saameyn is-laba-laab ah; Kiristaalo Fe:LN ah ayaa loo isticmaali karaa kaydinta holographic ee mugga indhaha.
