Finding a hidden state opens a path to dissipationless quantum electronics

December 3, 2018

Researchers discovered that a hidden ferromagnetic insulating (FMI) state emerged in Sr2Fe1+xRe1-xO6 films when the material’s local ionic order was disturbed by a small modification in cation ratio.1 This work provides a promising new route to developing

Brillouin Light Scattering has revealed the presence of an interfacial layer that controls mechanical reinforcement. By fitting BLS data (red) with a continuum model (blue) the shear modulus of the interface was determined. Inset: The BE SPM work has enab

Key to mechanical reinforcement of glassy polymer nanocomposites has been unraveled

July 26, 2016

Scientists have unraveled details of the mechanism of mechanical reinforcement in glassy polymer nanocomposites.1 Measurements in the interfacial layer ~2–4 nm around nanoparticles revealed that Young’s modulus, which defines the relationship between

Synthesis of two-dimensional GaSe/MoSe2 misfit heterojunctions by van der Waals epitaxy

April 26, 2016

Misfit heterojunctions formed by van der Waals (vdW) epitaxial growth of one crystalline metal chalcogenide monolayer on another was demonstrated for the first time to form p-n junctions that exhibit a photovoltaic response.

Listening to Materials at the Nanoscale

February 2, 2016

The detection of local phase transitions remains challenging, and to date most techniques can detect properties that change at macroscopic scales or at atomic scales, but virtually no technique offers the ability to monitor and map bias-induced phase trans
