LiTaO3 Substrate Tsanangudzo
LiTaO3 (lithium tantalate) substrate inoreva chinhu chine crystalline chinowanzoshandiswa mumhando dzakasiyana dzemagetsi uye optoelectronic application.Heano mamwe mapoinzi akakosha nezveLiTaO3 substrates:
1. Crystal structure: LiTaO3 ine perovskite crystal structure, iyo inoratidzirwa ne-tatu-dimensional network structure yemaatomu eokisijeni umo lithiamu uye tantalum maatomu anotora nzvimbo dzakananga.
2. Piezoelectric properties: LiTaO3 yakanyanya piezoelectric, zvinoreva kuti inogadzira mutero wemagetsi kana ichiiswa kune mechanical stress uye zvakasiyana.Ichi chimiro chinoita kuti chishande mune akasiyana acoustic wave zvishandiso senge pamusoro acoustic wave (SAW) mafirita uye resonators.
3. Nonlinear optical properties: LiTaO3 inoratidzira yakasimba isina mutsara optical properties, ichiita kuti ibudise mafrequency matsva kana kuchinja maitiro echiedza chechiitiko kuburikidza nekubatana kusina mutsara.Inowanzo shandiswa mumidziyo inoshandisa yechipiri harmonic chizvarwa (SHG) kana optical parametric oscillation (OPO), senge frequency kaviri makristasi kana optical modulators.
4. Hwakawanda hwekujeka: LiTaO3 ine huwandu hwakasiyana hwekujeka kubva kune ultraviolet (UV) kune infrared (IR) nharaunda.Inogona kufambisa mwenje kubva panosvika 0.38 μm kusvika 5.5 μm, ichiita kuti ive yakakodzera kune dzakasiyana siyana dzeoptoelectronic application dzinoshanda mumhando iyi.
5. High Curie tembiricha: LiTaO3 ine yakakwirira Curie tembiricha (Tc) pamusoro 610 ° C, iyo tembiricha apo ayo piezoelectric uye ferroelectric zvinhu zvinopera.Izvi zvinoita kuti ive yakakodzera kune yakakwira tembiricha yekushandisa senge yakakwira simba acoustic wave zvishandiso kana yakakwirira tembiricha sensors.
6. Kugadzikana kwemakemikari: LiTaO3 inogadzikana nemakemikari uye inopesana neakawanda anowanikwa solvents uye acids.Uku kugadzikana kunovimbisa kusimba uye kuvimbika kweiyo substrate mumamiriro akasiyana ekushanda uye nharaunda.
7. Yakanaka ma mechanical uye thermal properties: LiTaO3 ine simba rakanaka remagetsi uye kugadzikana kwekupisa, zvichiita kuti ikwanise kumira kushushikana kwemagetsi uye kupisa kwepamusoro pasina kukanganisa kwakanyanya kana kuora.Izvi zvinoita kuti ive yakakodzera kushandiswa kwemagetsi epamusoro kana nharaunda dzine hutsinye hwemagetsi kana mamiriro ekupisa.
LiTaO3 substrates inoshandiswa zvakanyanya mumashandisirwo akasiyana siyana anosanganisira SAW zvishandiso, frequency doubling madivayiri, optical modulators, optical waveguides, etc. Kusanganiswa kwayo kwepiezoelectric uye nonlinear optical properties, hupamhi hwekujeka, high Curie tembiricha, kugadzikana kwemakemikari, uye yakanaka mechanical uye thermal. zvivakwa zvinoita kuti zvive zvinhu zvakasiyana-siyana mumunda wemagetsi uye optoelectronics.
