KTaO3 Substrate Definition
KTaO3 (potassium tantalate) substrate yog hais txog crystalline substrate ua los ntawm cov compound potassium tantalate (KTaO3).
KTaO3 yog cov khoom siv perovskite nrog lub cubic siv lead ua zoo ib yam li SrTiO3.KTaO3 substrate muaj cov khoom uas ua rau nws muaj txiaj ntsig tshwj xeeb hauv ntau yam kev tshawb fawb thiab kev siv cuab yeej siv.Lub siab dielectric tas li thiab zoo hluav taws xob conductivity ntawm KTaO3 ua rau nws tsim nyog rau daim ntaub ntawv xws li capacitors, nco pab kiag li lawm, thiab high-frequency hluav taws xob circuits.Tsis tas li ntawd, KTaO3 substrates muaj cov khoom piezoelectric zoo heev, ua rau lawv muaj txiaj ntsig zoo rau kev siv piezoelectric xws li sensors, actuators, thiab cov khoom siv hluav taws xob.
Cov nyhuv piezoelectric tso cai rau KTaO3 substrate los tsim cov nqi thaum raug kev ntxhov siab los yog cov neeg kho tshuab deformation.Tsis tas li ntawd, KTaO3 substrates tuaj yeem pom ferroelectricity ntawm qhov kub thiab txias, ua rau lawv muaj feem cuam tshuam rau kev kawm ntawm condensed teeb meem physics thiab kev loj hlob ntawm nonvolatile nco li.
Zuag qhia tag nrho, KTaO3 substrates ua lub luag haujlwm tseem ceeb hauv kev tsim cov khoom siv hluav taws xob, piezoelectric, thiab ferroelectric.Lawv cov khoom xws li siab dielectric tas li, zoo hluav taws xob conductivity, thiab piezoelectricity ua rau lawv zoo tagnrho substrate cov ntaub ntawv rau ntau yam kev siv.
Superconducting Thin Films Txhais
Ib zaj duab xis superconducting yog hais txog ib txheej nyias ntawm cov khoom siv superconductivity, uas yog, muaj peev xwm ua hluav taws xob tam sim no nrog xoom tsis kam.Cov yeeb yaj kiab no feem ntau yog tsim los ntawm kev tso cov khoom siv superconducting mus rau hauv cov substrates siv ntau hom kev tsim xws li lub cev vapor deposition, tshuaj vapor deposition, los yog molecular beam epitaxy.
