Nanowire Arrays for Piezoelectric Energy Harvesting
Electrosciences' Director Markys Cain worked with the European team involved in the development of nanowire energy harvesting technologies. Their most recent publication, 'Area-Selective Growth of Zinc Oxide Nanowire Arrays for Piezoelectric Energy Harvesting' is available online. Electrosciences' contributions included the use of their most recent addition to the ESPY family range of measurement instruments - [...]
Giant electrostriction in single crystals
Giant strains in single crystals of an age old material - a new investigation highlights the importance of atomic defects on performance and durability. A new paper, co-authored by Electrosciences, is published in Applied Physics Letters, Materials. Video of the temperature dependence of XRD scans showing the evolution of the [...]
Simultaneous Large Optical and Piezoelectric Effects
A new paper, co-authored by Electrosciences, is published in Applied Physics Letters. 3D Evolution of the (220) reciprocal space (diffracting) volume during loading and unloading cycles. Electrical switching of ferroelectric domains and subsequent domain wall motion promotes strong piezoelectric activity, however, light scatters at refractive index discontinuities such [...]
Room-temperature multiferroic behavior in layer-structured Aurivillius phase ceramics
A new paper, co-authored by Electrosciences, is published in Applied Physics Letters. Spin density of the system (isosurface level 1⁄4 0.005): O (red), Bi (pink), La (green), Ti (light blue), Co (dark blue), and Fe (yellow) atoms. Multiferroics that simultaneously exhibit ferroelectricity and ferromagnetism have recently attracted great attention due [...]
In Situ Electric-Field Study of Surface Effects in Domain Engineered Crystals by Grazing Incidence Diffraction
A new paper, co-authored by Electrosciences, is published in Crystals. Software tools developed to create HKL reciprocal lattice maps In this work, we present a grazing incidence X-ray diffraction study of the surface of a 0.24Pb(In1/2Nb1/2)O3-Pb(Mg1/3Nb2/3)O3-PbTiO3 (PIN-PMN-PT) [011] poled rhombohedral single crystal. The near surface microstructure (the top several tens [...]
Higher efficiency sonar supported by new measurements
A new paper, co-authored by Electrosciences, points to new ways to control high powered sonar projectors using some of the newest single crystal piezoelectric materials that are becoming commercially available. Experimental measurements taken by Electrosciences in collaboration with the UK XMaS beamline at the ESRF, France, highlights the requirement to control the [...]
Is Fe doped BTO multiferroic?
New work just publsihed in APL-Materials shows that iron doped ferroelectric barium titanate exhibits multiferroic behaviour. New techniques developed under the European Metrology project 'ADVENT' by Electrosciences Ltd and the XMaS beamline at the ESRF (Synchrotron beamline in Grenoble, France) have shed new light on these materials. Software tools developed [...]
Tiny piezoelectronic device accelerates CMOS chips
Electrosciences is partner on EU project PETMEM The electronics industry needs a new CMOS transistor technology, and the EU-funded PETMEM project undertook efforts to develop it. The resulting alternative, called a piezoelectronic transduction (PET) transistor, is predicted to be faster and more energy efficient than conventional CMOS transistor alternatives. The project's key [...]
Room temperature multiferroic
New paper published: 'Bi3.25La0.75Ti2.5Nb0.25(Fe0.5Co0.5)0.25O12, a single phase room temperature multiferroic' J. Mater. Chem. C, 2018, 6, 2733 Multiferroics (MFs) have attracted great research interest due to the coexistence of ferroelectric and magnetic ordering, as well as magnetoelectric (ME) coupling. At present, there is a very limited number of single-phase MFs known and these [...]
