Physicists engineer new property out of 'white' graphene

Ultrathin materials made of a single layer of atoms have riveted scientists' attention since the discovery of the first such material—graphene—about 17 years ago. Among other advances since then, researchers including ...

Physics researchers discover new electronic phenomenon

Physics researchers at the University of North Florida's Atomic LEGO Lab discovered a new electronic phenomenon they call "asymmetric ferroelectricity." The research led by Dr. Maitri Warusawithana, UNF physics assistant ...

Oxygen migration enables ferroelectricity on nanoscale

Hafnium-based thin films, with a thickness of only a few nanometres, exhibit an unconventional form of ferroelectricity. This allows the construction of nanometre-sized memories or logic devices. However, it was not clear ...

Discovery could lengthen lifespan of electronic devices

Nobel laureate Herbert Kroemer once famously asserted "The interface is the device." The observations by the Sydney researchers could therefore spark a new debate on whether interfaces—which are physical boundaries separating ...

Natural three-dimensional nonlinear photonic crystal

Nonlinear photonic crystals (NPCs) are transparent materials that have a spatially uniform linear susceptibility, yet a periodically modulated quadratic nonlinear susceptibility. These engineered materials are used extensively ...
