The general objective is to study the effects of dimensionality reduction on structural, electronic and reaction properties in oxide materials. Our studies are carried out using a combination of laboratory and large instrument experimental techniques and theoretical tools. The experimental techniques used are photoemission spectroscopy, infrared spectroscopy, near-field microscopy and high resolution electron energy loss spectroscopy. The theoretical tools used are ab initio atomistic calculations.
Simulations are used to rationalise the formation principle of 2D transition metal mixed oxides.
Figure: The low dimensionality of the oxide impacts the redox process between the two cations which favours the formation of mixed compounds.
