Mechanically controllable nonlinear dielectrics

Strain-sensitive barium strontium titanate (Bax-Sr1-x-TiO3) perovskite systems are widely used for their superior nonlinear dielectric behaviors. In a new report on Science Advances, D.L. Ko and a research team in materials ...

Quantum thermal transistor can control heat currents

(Phys.org)—Researchers have designed a quantum thermal transistor that can control heat currents, in analogy to the way in which an electronic transistor controls electric current. The thermal transistor could be used in ...

Study reveals missing boundary in PZT phase diagram

(Phys.org) —Piezoelectric materials, which produce electricity in response to mechanical stress, account for a $12 billion global industry that is projected to grow at a rate of 13.2% per year, according to a recent report ...

Fabricating 3D Photonic Crystals

(PhysOrg.com) -- “In photonic crystals, the ability to control the structure of a material in full three dimensional space, allows you to control the way that light flows through it,” John Rogers tells PhysOrg.com. “This ...

A method for chemically tailoring layered nanomaterials

A new process that lets scientists chemically cut apart and stitch together nanoscopic layers of two-dimensional materials—like a tailor altering a suit—could be just the tool for designing the technology of a sustainable ...

Shaping the future of light through reconfigurable metasurfaces

The technological advancement of optical lenses has long been a significant marker of human scientific achievement. Eyeglasses, telescopes, cameras, and microscopes have all literally and figuratively allowed us to see the ...
