High-harmonic generation (HHG) is a nonlinear optical phenomenon through which high harmonics of an intense laser beam are generated in a target material, typically a gas. Physicists have been studying HHG in atomic gases ...
(Phys.org) —In the world of organic solar cells, polymer-based devices may currently be at the top, but other organic materials such as "small molecules" also prove to be promising. Although small-molecule organic solar ...
(Phys.org) -- While quantum dot-based light-emitting diodes (QLEDs) are not made of organic materials, they share many of the same advantages as organic LEDs (OLEDs). For instance, both QLEDs and OLEDs outshine semiconductor-based ...
(PhysOrg.com) -- When light passes through materials that we consider opaque, such as paint, biological tissue, fabric and paper, it is scattered in such a complex way that an image does not come through. "It is possible ...
A new family of materials that could result in improved digital information storage and uses less energy may be possible thanks to a team of Penn State researchers who demonstrated ferroelectricity in magnesium-substituted ...
