ʻO ka wehewehe ʻana o ka substrate LiNbO3:

LiNbO3 (lithium niobate) substrate e pili ana i kahi mea crystalline i hoʻohana mau ʻia ma ke ʻano he substrate a i ʻole substrate i nā mea uila a me optoelectronic like ʻole.Eia kekahi mau mea nui e pili ana i nā substrates LiNbO3:

1. ʻO ka hana aniani: ʻO LiNbO3 kahi aniani ferroelectric me kahi ʻano perovskite.Loaʻa iā ia nā ʻātoma lithium (Li) a me ka niobium (Nb) i hoʻonohonoho ʻia i loko o kahi lattice kristal kikoʻī.

2. Piezoelectric waiwai: LiNbO3 ikaika piezoelectric waiwai, 'o ia hoʻi, hana ia i nā koina uila ke hoʻokau 'ia i ka mechanical stress a me ka hope.He mea kūpono kēia waiwai no nā noi e like me nā mea hawewe acoustic, sensor, actuators, etc.

3. Nā waiwai Photoelectric: Loaʻa iā LiNbO3 nā waiwai optical a me electro-optic maikaʻi loa.Loaʻa iā ia kahi kuhikuhi refractive kiʻekiʻe, haʻahaʻa māmā absorption, a hōʻike i kahi hanana i kapa ʻia ʻo ka hopena electro-optic, kahi e hiki ke hoʻololi ʻia kāna kuhikuhi kuhikuhi e kahi kahua uila waho.Hoʻohana kēia mau waiwai i nā noi e like me nā modulators optical, nā alakaʻi nalu, nā pālua pinepine, a me nā mea hou aku.

4. Ka laulā ākea: LiNbO3 he ākea ākea, hiki iā ia ke hoʻouna i ka mālamalama i ka ʻike ʻike a kokoke i ka infrared spectrum.Hiki ke hoʻohana ʻia no ka hana ʻana i nā mea ʻenehana e hana ana ma kēia mau wahi lōʻihi hawewe.

5. Ka ulu ʻana a me ka hoʻonohonoho ʻana: Hiki ke hoʻonui ʻia nā kristal LiNbO3 me ka hoʻohana ʻana i nā ʻano like ʻole e like me Czochralski a me nā ʻenehana ulu ʻana o ka hopena top-seeded.Hiki ke ʻoki ʻia a hoʻonohonoho ʻia ma nā ʻaoʻao crystallographic ʻokoʻa e loaʻa ai nā pono kikoʻī a me nā pono uila e pono ai no ka hana ʻana i nā mea hana.

6. Kiʻekiʻe mechanical a me kemika paʻa: LiNbO3 mea mechanically a me kemika paʻa, hiki iā ia ke kuʻi.
