Epitaxial strain to get transparent materials

The ICN2 has participated in a research led by the ICMAB-CSIC and the ALBA Synchrotron to study the optical transport properties of transition metal oxides for photovoltaics applications.

There is an urgent need of metallic and transparent electrodes for applications in technologies such as flat panel displays or electrodes for photovoltaics that may replace the expensive and scarce Indium-Tin oxide (ITO). SrVO3 (SVO) is a metallic and transparent in the visible optical range material that has been attracting attention recently.

Dr José Santiso, from the ICN2 Nanomaterials Growth Unit, has participated in a research led by the ICMAB-CSIC and the ALBA Synchrotron in which they have been able to show that epitaxial strain acting on SVO thin films enables the modulation of the plasma frequency of the films, allowing to modify the transparency window limit of the material. These results, which have just been published in Advanced Functional Materials, pave the way for tuning the optical transport properties for photovoltaics.
