Abstract: Transparent conducting oxides (TCOs) are key elements to many technological devices: displays, solar cells, smart windows, etc.
Whereas indium-tin-oxide (ITO) is unquestionably the most-widely used TCO, the scarcity and subsequent price increase of indium push research towards alternative materials, such as perovskite materials containing early transition metals.
This doctoral work is focused on the growth and characterization of thin films of SrVO3 and SrNbO3, which are among the best TCOs ever reported. It shall provide new views on correlated matter, including electronic and plasmonic excitations, and the subtle interplay between strain and hybridization in these thin films. Finally, the suitability in all-oxide heterostructures is explored.
