Gawo la KTaO3
Kufotokozera
Potaziyamu tantalate single crystal ndi mtundu watsopano wa kristalo wokhala ndi perovskite ndi pyrochlore structure.Ili ndi chiyembekezo chachikulu chamsika pakugwiritsa ntchito makanema owonda kwambiri a superconducting.Itha kupereka magawo a kristalo amodzi amitundu yosiyanasiyana komanso mawonekedwe abwino kwambiri.

Kutanthauzira kwa KTaO3 Substrate
Gawo la KTaO3 (potaziyamu tantalate) limatanthawuza gawo lapansi la crystalline lopangidwa ndi potaziyamu tantalate (KTaO3).
KTaO3 ndi zinthu za perovskite zokhala ndi mawonekedwe a kristalo wa cubic ofanana ndi SrTiO3.Gawo la KTaO3 lili ndi zinthu zomwe zimapangitsa kuti zikhale zothandiza kwambiri pakufufuza ndi kugwiritsa ntchito zida zosiyanasiyana.Ma dielectric okhazikika komanso abwino amagetsi a KTaO3 amapangitsa kuti ikhale yoyenera kugwiritsa ntchito monga ma capacitor, zida zokumbukira, komanso ma frequency amagetsi apamwamba kwambiri.Kuphatikiza apo, ma substrates a KTaO3 ali ndi zida zabwino kwambiri za piezoelectric, zomwe zimawapangitsa kukhala othandiza pakugwiritsa ntchito ma piezoelectric monga masensa, ma actuators, ndi zokolola mphamvu.
Mphamvu ya piezoelectric imalola gawo lapansi la KTaO3 kupanga zolipiritsa zikakumana ndi kupsinjika kwamakina kapena kupunduka kwamakina.Kuphatikiza apo, ma substrates a KTaO3 amatha kuwonetsa ferroelectricity pa kutentha kotsika, kuwapangitsa kukhala oyenera pophunzira za fiziki ya zinthu zofupikitsidwa komanso kupanga zida zokumbukira zosasinthika.
Ponseponse, magawo a KTaO3 amagwira ntchito yofunika kwambiri pakupanga zida zamagetsi, piezoelectric, ndi ferroelectric.Makhalidwe awo monga high dielectric constant, conductivity yabwino yamagetsi, ndi piezoelectricity amawapanga kukhala zipangizo zoyenera zapansi pa ntchito zosiyanasiyana.
Superconducting Thin Films Tanthauzo
Kanema wowonda kwambiri wa superconducting amatanthawuza chinthu chochepa kwambiri chokhala ndi superconductivity, ndiko kuti, kuthekera koyendetsa magetsi ndi zero kukana.Makanemawa nthawi zambiri amapangidwa poyika zida zopangira ma superconducting pamagawo pogwiritsa ntchito njira zosiyanasiyana zopangira monga kuyika kwa nthunzi, kuyika kwa nthunzi wamankhwala, kapena ma molecular beam epitaxy.
