Visualização de estrutura de domínios em cerâmicas e nanoestruturas ferroelétricas via microscopia de piezoresposta
(Universidade Federal de São CarlosBRUFSCarPrograma de Pós-Graduação em Física - PPGF, 2013-02-27)
In this work, the domain structure of a transparent ferroelectric ceramic of (Pb0,79La0,21)TiO3 (PLT 21) was investigated in detail by piezoresponse force microscopu (PFM) and a protocol of measurements and analysis of the ...
Effect of oxidizing and reducing atmospheres on Ba(Ti0.90 Zr0.10)O3:2V ceramics as characterized by piezoresponse force microscopy
(2011)
The effect of annealing atmospheres (Atamb, N2 and O2) on the electrical properties of Ba(Ti0.90Zr0.10 )O3:2V (BZT10:2V) ceramics obtained by the mixed oxide method was investigated. X-ray photoelectron spectroscopy (XPS) ...
Domínios ferroelétricos em cerâmicas e materiais nanoestruturados: investigação por microscopia de piezoresposta
(Universidade Federal de São CarlosBRUFSCarPrograma de Pós-Graduação em Física - PPGFCâmpus São Carlos, 2011-12-07)
In this work, ferroelectric domain structure was investigated by Piezoresponse Force Microscopy (PFM). To this, an Atomic Force Microscope (AFM) has been modified to use it as PFM at room temperature and at high temperatures. ...
Structural and local physical properties of relaxor ferroelectric thin films
(Universidade Estadual Paulista (Unesp), 2017-09-11)
Polycrystalline thin films of Pb0.91La0.09Zr0.65Ti0.35O3 (PLZT9/65/35) and Sr0.75Ba0.25Nb2O6 (SBN75) were prepared by the chemical polymeric routine in order to investigate their physical properties at the macro- and ...
