This year we can accept up to two M1 students. If you wish to enter the doctoral course, please contact us.
All projects in this laboratory involve thin films of transition metal oxides. There are many interesting oxides, such as high-temperature superconductors, photocatalysts, magnetic materials, ferroelectrics, multiferroics, semiconductors, wide-gap dieectrics, etc. We study many different materials, but usually in the form of very thin layers, in heterostructures or in the form of nanostructures.
We offer projects related to:
Crystal is grown one atomic layer or unit cell at a time. This is a useful technique for materials design, making nanostructures, heterostructures, and electronic device structures, such as transistors or tunnel junctions. Some examples of topics on offer to new students:
Ordered perovskite structures offer new and interesting ways of
constructing polar and ferroelectric materials. Ordering can be seen
by x-ray diffraction analysis. Ferroelectricity is related to
bond length variations.
Magnetoelastic coupling is studied in nanostructured thin films, such as arrays of magnetite nanopyramids. This project is suitable for students interested in new materials development.
New projects in this area are related to developing new types of heterostructures for photo- catalysis. The work involves heterostructure growth and electrochemical characterization.
Platinum-group elements in oxides are less common, but offer a number of interesting possibilities for materials design. Pt, Ir, Rh, etc. are well-known catalytic materials. We are interested in nanostructured Ir and Pt for catalysis. Another reson to study iridates is the strong spin-orbit coupling and interesting magnetic states in magnetically frustrated iridate pyrochlores.
New projects in this area are related to developing new types of heterostructures for photocatalysis and for looking at scattering or localization mechanisms in quai-two-dimensional systems. The work involves heterostructure growth and transport characterization.
Layered oxide structures create natural barrier layers in a crystal, resulting in highly anisotropic physical properties. In this project we mostly look at transport, magnetic behavior and carrier density control in 2-dimensional interface layers. The project is suitable for students interested in device design on an atomic scale. It is also possible to focus either on synthesis and measurement or on analysis of transport data.
Oxide materials can have very complicated crystal structures due to the large number of different cations in the lattice. The surface structures are therefore often poorly known. We offer a possibility to study the atomic-scale structure of oxide materials by various surface analysis techniques, including STM and AFM, either x-ray or electron diffraction, LEED analysis, and by ion scattering spectroscopy. This project is suitable for students interested in functional materials and surface design or for students who would like to work on surface science oriented topics.
