Flexoelectricity and surface ferroelectricity of water ice - Nature Physics

Ice is not piezoelectric, despite the polarity of water molecules, but bending ice may produce electricity. This has now been experimentally demonstrated, with a flexoelectric coefficient comparable to that of common ceramic materials.

In 1920, Joseph Valasek explained ferroelectricity, the electrical polarization of certain materials.

Excited to share a new colloquium by Prof. Andrea Cavalleri, a founding director of the MPI for the Structure and Dynamics of Matter 🎓✨ In his Nordita talk, he explores how coherent electromagnetic radiation can induce unexpected phases like magnetic order, ferroelectricity, and high-temperature superconductivity.

Full abstract: In this colloquium, I will discuss how coherent electromagnetic radiation, when tuned to drive collective modes in quantum materials, can be used to induce unexpected dynamical phases. An illustrative set of examples will be discussed for the nonlinear control of the crystal lattice, which is used to induce magnetic order in paramagnetic materials, ferroelectricity in paraelectrics, non-equilibrium superconductivity at high temperatures, and other dynamical phases. These studies open up new directions in fundamental research but also expose a set of phenomena that will inevitably be encountered if one wishes to use quantum materials in ultra-high bit-rate applications.

A general theory to realize bilayer stacking ferroelectricity

Two-dimensional (2D) ferroelectrics, planar materials that have a spontaneous and reversible electric polarization, are extremely rare and yet could be extremely advantageous for the development of new nanoelectronics. Due to their ferroelectric properties and thin nature, they could be used to create high-performing, small and flexible devices, including high-density non-volatile memory, optoelectronics, ultra-low energy electronics and wearable technologies.
