Discovery and tuning of new TCOs based perovskites – DisTCOvery

Due to high critical scarcity for doped semiconductor indium-tin-oxide (ITO), new transparent conducting oxides (TCOs) need to be developed. Recently, new TCOs have been discovered based on strongly correlated electron SrVO3 and CaVO3 phases. These compounds belong to the very rich perovskite family ABO3 (with A: alkaline earth, and B: transition metal) The multiple cationic substitutions at A and/or B sites, can act on the performance of those TCOs such as electronic correlations, bandfilling, … Therefore, in the project DisTCOvery, we have selected some A and B cations, which will be a powerful platform to tune and improve the functional properties (conductivity, transparency) of new perovskite-based TCOs thin films. We will be also able to induce new properties that are absent in other TCOs such as magnetism, which may unlock opportunities for multifunctional devices in the design of next-generation displays and photovoltaics. Finally, we will integrate these new TCOs on glass thanks to 2D nanosheets used as seed layer. Thus, different nanosheets will be developed in line with the different lattice parameters of the TCOs that one wishes to crystallize in order to propose a technological solution for their integration into devices.
