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.

A new step in the development of self-shaping materials

Researchers from the ICN2 Supramolecular NanoChemistry and Materials Group, led by ICREA Prof. Daniel Maspoch, have developed a procedure to obtain films that can adopt programmed shapes. Published in Advanced Materials, the method is based on the use of flexible submicrometric crystals that increase in size when humidified. The resulting films could serve as autonomous mechanical devices, having potential applications in micromanipulation, automation, and robotics.
