KTaO3 Substrate Tsanangudzo
KTaO3 (potassium tantalate) substrate inoreva crystalline substrate yakagadzirwa nekomboni potassium tantalate (KTaO3).
KTaO3 ndeye perovskite zvinhu zvine cubic crystal chimiro chakafanana neSrTiO3.Iyo KTaO3 substrate ine zvivakwa zvinoita kuti inyanyo batsira mumhando dzakasiyana dzekutsvagisa uye zvishandiso zvekushandisa.Iyo yakakwira dielectric inogara uye yakanaka magetsi conductivity yeKTaO3 inoita kuti ive yakakodzera kune maapplication akadai sema capacitors, ndangariro zvishandiso, uye yakakwirira-frequency emagetsi maseketi.Pamusoro pezvo, KTaO3 substrates ine yakanakisa piezoelectric zvivakwa, zvichiita kuti zvive zvakakosha kune piezoelectric application senge masensor, actuators, uye simba kukohwa.
Iyo piezoelectric mhedzisiro inobvumira iyo KTaO3 substrate kuburitsa machaji kana ichiiswa kune mechaniki kusagadzikana kana mechanical deformation.Pamusoro pezvo, KTaO3 substrates inogona kuratidza ferroelectricity patembiricha yakaderera, ichiita kuti ive yakakosha pakudzidza kweyakapfupikiswa nyaya fizikisi uye kuvandudzwa kwezvisina kuvhurika ndangariro.
Pakazere, KTaO3 substrates inoita basa rakakosha mukuvandudzwa kwemagetsi, piezoelectric, uye ferroelectric zvishandiso.Zvimiro zvavo senge yakakwira dielectric kugara, yakanaka magetsi conductivity, uye piezoelectricity inoita kuti ive yakakodzera substrate zvinhu zvekushandisa kwakasiyana siyana.
Superconducting Thin Films Tsanangudzo
Iyo superconducting yakaonda firimu inoreva hutete hwezvinhu zvine superconductivity, ndiko kuti, kugona kuitisa magetsi ne zero kuramba.Aya mafirimu anowanzo gadzirwa nekuisa superconducting zvinhu pa substrates vachishandisa nzira dzakasiyana-siyana dzekugadzira senge yemuviri mhute deposition, kemikari vapor deposition, kana molecular beam epitaxy.
