Donor-doping and reduced leakage current in Nb-doped Na0.5Bi0.5TiO3 (2015)
Journal Article
Li, M., Li, L., Zang, J., & Sinclair, D. C. (2015). Donor-doping and reduced leakage current in Nb-doped Na0.5Bi0.5TiO3. Applied Physics Letters, 106(10), Article 102904. https://doi.org/10.1063/1.4914509

Low levels of so-called “donor-doping” in titanate-based perovskite oxides such as La for Ba, Sr, and Nb for Ti in (Ba, Sr)TiO3 can significantly reduce the resistivity of these typical (d0) dielectric materials and expand application areas to positi...

Computational identification and experimental realization of lithium vacancy introduction into the olivine LiMgPO4 (2015)
Journal Article
Enciso-Maldonado, L., Dyer, M. S., Jones, M. D., Li, M., Payne, J. L., Pitcher, M. J., Omir, M. K., Claridge, J. B., Blanc, F., & Rosseinsky, M. J. (2015). Computational identification and experimental realization of lithium vacancy introduction into the olivine LiMgPO4. Chemistry of Materials, 27(6), 2074-2091. https://doi.org/10.1021/cm504518q

Calculation of the energetics of aliovalent substitution into the olivine LiMgPO4 suggests that replacement of Mg2+ by In3+ is the most effective way to introduce lithium vacancies and thus generate Li ion conductivity. Experimental synthesis accesse... Read More about Computational identification and experimental realization of lithium vacancy introduction into the olivine LiMgPO4.
