Optimizing thermal conduction in bulk polycrystalline $ SrTiO_{3−δ} $ ceramics via oxygen non-stoichiometry
Abstract while $ SrTiO_{3} $ exhibits promising electronic transport properties, its high thermal conductivity (κ) is detrimental for its use as a thermoelectric material. Here, we investigate the influence of oxygen non-stoichiometry on κ in bulk $ SrTiO_{3} $ ceramics. A significant reduction in κ...

Here, we investigate the influence of oxygen non-stoichiometry on κ in bulk $ SrTiO_{3} $ ceramics. A significant reduction in κ was achieved in oxygen deficient $ SrTiO_{3−δ} $, owing to the presence of oxygen vacancies that act as phonon scattering centers. Upon oxidation of $ SrTiO_{3−δ} $, the κ of pristine $ SrTiO_{3} $ was recovered, suggesting that oxygen vacancies were indeed responsible for the reduction in κ. Raman spectroscopy was used as an independent tool to confirm the reduction of oxygen vacancies in $ SrTiO_{3−δ} $ upon oxidation. | ||

Here, we investigate the influence of oxygen non-stoichiometry on κ in bulk $ SrTiO_{3} $ ceramics. A significant reduction in κ was achieved in oxygen deficient $ SrTiO_{3−δ} $, owing to the presence of oxygen vacancies that act as phonon scattering centers. Upon oxidation of $ SrTiO_{3−δ} $, the κ of pristine $ SrTiO_{3} $ was recovered, suggesting that oxygen vacancies were indeed responsible for the reduction in κ. Raman spectroscopy was used as an independent tool to confirm the reduction of oxygen vacancies in $ SrTiO_{3−δ} $ upon oxidation.</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Bhattacharya, Sriparna</subfield><subfield code="e">verfasserin</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Darroudi, Taghi</subfield><subfield code="e">verfasserin</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Karakaya, Mehmet</subfield><subfield code="e">verfasserin</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Kucera, Courtney</subfield><subfield code="e">verfasserin</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Ballato, John</subfield><subfield code="e">verfasserin</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Adebisi, Rasheed</subfield><subfield code="e">verfasserin</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Gladden, Joseph R.</subfield><subfield code="e">verfasserin</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Podila, Ramakrishna</subfield><subfield code="e">verfasserin</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Rao, Apparao M.</subfield><subfield code="e">verfasserin</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Alshareef, Husam N.</subfield><subfield code="e">verfasserin</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Tritt, Terry M.</subfield><subfield code="e">verfasserin</subfield><subfield code="4">aut</subfield></datafield><datafield tag="773" ind1="0" ind2="8"><subfield code="i">Enthalten in</subfield><subfield code="t">MRS communications</subfield><subfield code="d">Berlin : Springer, 2011</subfield><subfield code="g">8(2018), 4 vom: 14.

Optimizing thermal conduction in bulk polycrystalline $ SrTiO_{3−δ} $ ceramics via oxygen non-stoichiometry |
| abstract |
Abstract while $ SrTiO_{3} $ exhibits promising electronic transport properties, its high thermal conductivity (κ) is detrimental for its use as a thermoelectric material. Here, we investigate the influence of oxygen non-stoichiometry on κ in bulk $ SrTiO_{3} $ ceramics. A significant reduction in κ was achieved in oxygen deficient $ SrTiO_{3−δ} $, owing to the presence of oxygen vacancies that act as phonon scattering centers. Upon oxidation of $ SrTiO_{3−δ} $, the κ of pristine $ SrTiO_{3} $ was recovered, suggesting that oxygen vacancies were indeed responsible for the reduction in κ. Raman spectroscopy was used as an independent tool to confirm the reduction of oxygen vacancies in $ SrTiO_{3−δ} $ upon oxidation. |
