Driscoll Research Group

 

We work on a range of functional oxides for energy devices, with properties from superconductivity to ionics to semiconducting, for applications in power transmission to fuel cells and solid state batteries and lighting to energy harvesting and storage.

 

Two Example Studies:

a) Enhancing Energy Storage in Ferroelectrics

We used Sm doping to nanoengineer the complex (Bi,Sm)FeO3-Ba(Ti,Sm)O3 ferroelectric to have polar nanoclusters. Work done in this area via collaboration with Tsinghua Univ., China via visiting PhD student, Hao Pan, and also with Dr. Ahmed Kursumovic in Driscoll group.

b) Inducing High Oxide Ionic Conductivity by Stabilising doped d- Bi2O3

We demonstrate for the first time the growth of epitaxially stabilised highly ionically conducting Dy doped- δ-Bi2O3 which is not normally stable at lower operation temperatures. While some approaches using lateral epitaxial strain have been used, these have severe thickness limitations. Here, using a vertical nanocomposite approach, we were able to stabilise films to over 100 nm. Very high ionic conductivity values reaching 10−3 S cm−1 at 500 °C were achieved.

Prof. Driscoll warmly welcomes enquiries from prospective students, post-docs or visitors who are interested in working with us or learning more about what we do.
