Thermoelectric crystal conductivity reaches a new high

Nov 26, 2021 (Nanowerk News) Just as a voltage difference can generate electric current, a temperature difference can generate a current flow in thermoelectric materials governed by its “Peltier conductivity” (P). Now, researchers from Japan demonstrate an unprecedented large P in a single crystal of Ta2PdSe6 that is 200 times...

using an antiferromagnet for solid devices

Nov 24, 2021 (Nanowerk News) Researchers at the Max Planck Institute for Chemical Physics of Solids in Dresden, Germany, together with collaborators at the Ohio State University and the University of Cincinnati, have discovered, for the first time, a giant thermoelectric effect in an antiferromagnet. The study, published in Nature...

Scientists successfully manipulate a single skyrmion at room temperature

Nov 24, 2021 (Nanowerk News) Scientists from the RIKEN Center for Emergent Matter Science and collaborators have shown that they can manipulate single skyrmions—tiny magnetic vortices that could be used as computing bits in future ultra-dense information storage devices—using pulses of electric current, at room temperature. Skyrmions—tiny particles that can...

Doing photon upconversion a solid

Nov 25, 2021 (Nanowerk News) Solid-solution organic crystals have been brought into the quest for superior photon upconversion materials, which transform presently wasted long-wavelength light into more useful shorter wavelength light. Scientists from Tokyo Institute of Technology revisited a materials approach previously deemed lackluster – using a molecule originally developed...
