Internal barrier layer capacitor, nearest neighbor hopping, and variable range hopping conduction in $ Ba_{1−x} $$ Sr_{x} $$ TiO_{3−δ} $ nanoceramics
Abstract The dielectric properties of the solid solution $ Ba_{1−x} $$ Sr_{x} $$ TiO_{3−δ} $ (0 ≤ x ≤ 1) have been investigated. The nanopowders were prepared via a coprecipitation reaction followed by a calcination treatment. Spark plasma sintering allowed to obtain dense nanocrystalline ceramics....

The nanopowders were prepared via a coprecipitation reaction followed by a calcination treatment. Spark plasma sintering allowed to obtain dense nanocrystalline ceramics. Broadband impedance spectroscopy revealed colossal permittivity (ε′ = $ 10^{5} $) associated with low losses (tan δ = 0.03) in the most favorable case. The bulk conductivity data was analyzed using Jonscher’s universal dielectric response model. In the Ba-rich compound, conduction process followed variable range hopping conduction model while the Sr-rich BST compound showed the nearest neighbor hopping conduction mechanism associated with displacements of space charges. These two different conduction mechanisms might be able to explain superior temperature–frequency-independent dielectric properties in Sr-rich BST compound compared to Ba-rich BST compound. | ||

The bulk conductivity data was analyzed using Jonscher’s universal dielectric response model. In the Ba-rich compound, conduction process followed variable range hopping conduction model while the Sr-rich BST compound showed the nearest neighbor hopping conduction mechanism associated with displacements of space charges. These two different conduction mechanisms might be able to explain superior temperature–frequency-independent dielectric properties in Sr-rich BST compound compared to Ba-rich BST compound.</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">BaTiO3</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Spark Plasma Sinter</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Barium Titanate</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Strontium Titanate</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Barium Strontium Titanate</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Kim, Ji Hyun</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Han, Hyuksu</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Dufour, Pascal</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Tenailleau, Christophe</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Nino, Juan Claudio</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Cordoncillo, Eloisa</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Beltran-Mir, Hector</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Dupuis, Sébastien</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Guillemet-Fritsch, Sophie</subfield><subfield code="4">aut</subfield></datafield><datafield tag="773" ind1="0" ind2="8"><subfield code="i">Enthalten in</subfield><subfield code="t">Journal of materials science</subfield><subfield code="d">Springer US, 1966</subfield><subfield code="g">51(2016), 16 vom: 12.

| abstract |
Abstract The dielectric properties of the solid solution $ Ba_{1−x} $$ Sr_{x} $$ TiO_{3−δ} $ (0 ≤ x ≤ 1) have been investigated. The nanopowders were prepared via a coprecipitation reaction followed by a calcination treatment. Spark plasma sintering allowed to obtain dense nanocrystalline ceramics. Broadband impedance spectroscopy revealed colossal permittivity (ε′ = $ 10^{5} $) associated with low losses (tan δ = 0.03) in the most favorable case. The bulk conductivity data was analyzed using Jonscher’s universal dielectric response model. In the Ba-rich compound, conduction process followed variable range hopping conduction model while the Sr-rich BST compound showed the nearest neighbor hopping conduction mechanism associated with displacements of space charges. These two different conduction mechanisms might be able to explain superior temperature–frequency-independent dielectric properties in Sr-rich BST compound compared to Ba-rich BST compound. © Springer Science+Business Media New York 2016 |
