Loaʻa i ka LiTaO3 ke aniani hoʻokahi electro-optic, piezoelectric a me nā waiwai pyroelectric, a hoʻohana nui ʻia i nā mea pyroelectric a me ka TV kala.

LiTaO3 Kahua Wahi
LiTaO3 (lithium tantalate) substrate e pili ana i kahi mea crystalline i hoʻohana mau ʻia i nā noi uila a me optoelectronic like ʻole.Eia kekahi mau mea nui e pili ana i nā substrate LiTaO3:
1. ʻO ka hoʻolālā aniani: LiTaO3 he perovskite crystal structure, kahi i hōʻike ʻia e kahi ʻano pūnaewele ʻekolu-dimensional o nā atomo oxygen kahi e noho ai nā lithium a me ka tantalum atoms i nā kūlana kikoʻī.
2. Nā waiwai piezoelectric: LiTaO3 he piezoelectric kiʻekiʻe loa, ʻo ia hoʻi, hoʻopuka ia i ka uku uila ke hoʻokau ʻia i ke koʻikoʻi mechanical a me ka hope.Hoʻohana kēia hiʻohiʻona i nā mea hana hawewe acoustic like ʻole e like me nā kānana a me nā resonators surface acoustic wave (SAW).
3. Nā waiwai ʻike ʻole linear: Hōʻike ʻo LiTaO3 i nā waiwai optical nonlinear ikaika, hiki iā ia ke hana i nā alapine hou a hoʻololi paha i nā hiʻohiʻona o ka mālamalama hanana ma o nā pilina nonlinear.Hoʻohana maʻamau ia i nā polokalamu e hoʻohana ana i ka hanauna harmonic lua (SHG) a i ʻole ka optical parametric oscillation (OPO), e like me nā kristal pālua pālua a i ʻole modulators optical.
4. Ka laulā ākea o ka ʻike: LiTaO3 he ākea ākea mai ka ultraviolet (UV) a i ka ʻāpana infrared (IR).Hiki iā ia ke hoʻouna i ka mālamalama mai kahi o 0.38 μm a i 5.5 μm, e kūpono ana i nā ʻano optoelectronic noi e hana ana i kēia pae.
5. Kiʻekiʻe Curie wela: LiTaO3 He kiʻekiʻe Curie wela (Tc) ma kahi o 610°C, ʻo ia ka mahana i nalowale ai kona mau waiwai piezoelectric a me ferroelectric.He kūpono kēia no nā noi wela kiʻekiʻe e like me nā mea hawewe acoustic mana kiʻekiʻe a i ʻole nā mea ʻike wela kiʻekiʻe.
6. Paʻa kemika: LiTaO3 paʻa kemika a kūpaʻa i nā mea hoʻoheheʻe maʻamau a me nā waikawa.Mālama kēia kūpaʻa i ka lōʻihi a me ka hilinaʻi o ka substrate i nā ʻano hana like ʻole a me nā kaiapuni.
7. ʻO nā waiwai mechanical a me ka wela maikaʻi: He ikaika ikaika ko LiTaO3 a me ke kūpaʻa wela, hiki iā ia ke kū i ke koʻikoʻi mechanical a me ka wela kiʻekiʻe me ka ʻole o ka deformation a i ʻole degradation.He mea kūpono kēia no nā noi mana kiʻekiʻe a i ʻole nā kaiapuni me nā kūlana mechanical a thermal paha.
Hoʻohana nui ʻia nā substrates LiTaO3 i nā noi like ʻole me nā mea SAW, nā mea pālua pinepine, nā modulators optical, nā alakaʻi nalu optical, a me nā mea ʻē aʻe. ʻO nā waiwai e lilo ia i mea versatile ma ke kahua o ka uila a me ka optoelectronics.
