    A Quasiparticle that can Transfer Heat under Electrical Control

    February 3, 2023, Categories  Physics, Technology/Electronics

    Because thermal conductivity in this class of materials can be changed with application of an external electric field at room temperature, they hold promise for use in heat switches for everyday applications, like collection of solar power.

    Scientists have found the secret behind a property of solid materials known as ferroelectrics, showing that quasiparticles moving in wave-like patterns among vibrating atoms carry enough heat to turn the material into a thermal switch when an electrical field is applied externally.

    A key finding of the study is that this control of thermal conductivity is attributable to the structure of the material rather than any random collisions among atoms...

    Three images showing production of ferroelectric magnesium-substituted zinc oxide thin films
    Part of the process of creating ferroelectric magnesium-substituted zinc oxide thin films include: (left) Image showing thin film being sputter-deposited from metal sources; (center) ferroelectric hysteresis loops of thin-film capacitors showing two remanent polarization states at zero field; (right) atomic force microscope image showing a smooth surface at the nanometer scale and a very fine-grained and fiber-textured microstructure.

    A new family of materials that could result in improved digital information storage and uses less energy may be possible thanks to a team of Penn State researchers who demonstrated ferroelectricity in magnesium-substituted zinc oxide.

    Ferroelectric materials are spontaneous electricly polarized bcause nega...

    Skyrmions, found in Magnetic Systems, now show to also exist in Ferroelectrics

    Schematic representation of the structure and dipolar configuration of the vortex state.

    Schematic representation of the structure and dipolar configuration of the vortex state. The structure consists of a cylindrical BaTiO3 (BTO) nanowire with a radius R of 2.7 nm (seven lattice constant units) embedded in a SrTiO3 (STO) matrix with lateral sides along the [100] and [010] directions of nx=ny=36 lattice constant units, and a length nz=6 along the [001] pseudocubic direction. (b) Cross-sectional dipolar configuration of the (Vxy|FEz) state characterized by a vortex pattern in the z-planes co-occurring with an electrical polarization along the [001] direction.

    Skyrmions are non-coplanar swirling field textures. Ferroelectrics convert changes in mechanical energy into electrical energy and vice versa...
