Intriguing behaviour of molybdenum diselenide at room temperature

A study recently published on Nano Letters has revealed interesting properties of monolayer molybdenum diselenide (MoSe2), which can open up to spintronic applications of this nanomaterial. A sample with a low concentration of dopants and many crystal defects has shown spin lifetimes of 100ns at room temperature and spin polarization reversal over 60K. Dr Zeila Zanolli, Ramon y Cajal researcher at the ICN2 Theory and Simulation Group, has played a fundamental role in the theoretical interpretation of these results.

Ferroelectric oxides in perovskite solar cells increase their stability

Researchers from the ICN2 Nanostructured Materials for Photovoltaic Energy Group and the Ecole Polytechnique Fédérale de Lausanne have used a ferroelectric oxide (PbZrTiO3) as an electron extraction material for stable halide perovskite solar cells. This complex oxide, used for the first time with this purpose, not only avoids the inconveniences of classical oxides such as TiO2, but also enhances the carrier transfer. This advancement was highlighted in the cover of Sustainable Energy and Fuels.
