BaTiO3 substrate
Tsanangudzo
BaTiO3makristasi ega ane yakanakisa photorefractive zvivakwa, yakakwira ratidziro ye-self-pumped phase conjugation uye maviri-wave musanganiswa (optical zoom) kunyatsoshanda muOptical information storage ine hombe inogona kushandiswa, inovawo yakakosha substrate zvinhu.

BaTiO3 Substrate Tsanangudzo
BaTiO3 substrate inoreva crystalline substrate yakagadzirwa nekomboni barium titanate (BaTiO3).BaTiO3 inonzi ferroelectric material ine perovskite crystal structure, iyo inoreva kuti ine zvinhu zvakasiyana-siyana zvemagetsi, zvichiita kuti zvive zvakanaka kune zvakasiyana-siyana zvekushandisa.
BaTiO3 substrates inowanzo shandiswa mumunda wekuonda firimu deposition, uye inonyanya kushandiswa kukura epitaxial matete mafirimu emhando dzakasiyana.Iyo crystalline chimiro cheiyo substrate inobvumira kurongeka chaiko kwemaatomu, ichigonesa kukura kwemhando yepamusoro mafirimu matete ane yakanakisa crystallographic zvimiro.Iyo ferroelectric zvimiro zveBaTiO3 zvakare inoita basa rakakosha mumashandisirwo akadai semagetsi uye ndangariro zvishandiso.Inoratidza polarization inongoerekana yaitika uye kugona kushandura pakati penyika dzakasiyana dzepolarization pasi pesimba rekunze kwemunda.
Ichi chivakwa chinoshandiswa mumatekinoroji akadai seasina-volatile memory (ferroelectric memory) uye electro-optical zvishandiso.Pamusoro pezvo, ma substrates eBaTiO3 ane maapplication mundima dzakasiyana senge piezoelectric zvishandiso, masensa, actuators, uye microwave zvikamu.Iyo yakasarudzika yemagetsi uye michina yeBaTiO3 inobatsira mukushanda kwayo, ichiita kuti ive yakakodzera kune aya maapplication.
