Breakthrough in Organic Electronics

Double doping could improve the light-harvesting efficiency of flexible organic solar cells (left), the switching speed of electronic paper (center) and the power density of piezoelectric textiles (right). Disclaimer: The image may only be used with referral to Epishine, as supplier of the flexible solar cell. For instance: 'The solar cell was supplied by Epishine AB.'

Researchers from Chalmers University of Technology, Sweden, have discovered a simple new tweak that could double the efficiency of organic electronics. OLED-displays, plastic-based solar cells and bioelectronics are just some of the technologies that could benefit from their new discovery, which deals with "double-doped"

Next-Generation Photonic Memory Devices are Light-Written

All-optical switching. Data is stored in the form of 'bits', which contains digital 0 (North Poles down) or 1 (North Poles up). Data writing is achieved by 'switching' the direction of the poles via the application of short laser pulses (in red).

Light is the most energy-efficient way of moving information. Yet, light shows one big limitation: it is difficult to store. As a matter of fact, data centers rely primarily on magnetic hard drives. However, in these hard drives, information is transferred at an energy cost that is nowadays exploding. Researchers

More Stable Light from Intentionally 'Squashed' Quantum Dots

Novel colloidal quantum dots are formed of an emitting cadmium/selenium (Cd/Se) core enclosed into a compositionally graded CdxZn1-xSe shell wherein the fraction of zinc versus cadmium increases towards the dot's periphery. Due to a directionally asymmetric lattice mismatch between CdSe and ZnSe, the core, at top right, is compressed more strongly perpendicular to the crystal axis than along it. This leads to modifications of the electronic structure of the CdSe core, which beneficially affects its light-emission properties. Bottom image: Experimental traces of emission intensity from a conventional quantum dot (upper panel) and a novel asymmetrically compressed quantum dot (lower panel) resolved spectrally and temporally. The emission from the conventional quantum dot shows strong spectral fluctuations ("spectral jumps" and "spectral diffusion"). The emission from the asymmetrically compressed quantum dots is highly stable in both intensity and spectral domains. In addition, it shows a much narrower linewidth, which is below the room-temperature thermal energy (25 meV).

LOS ALAMOS, N.M.--Intentionally "squashing" colloidal quantum dots during chemical synthesis creates dots capable of stable, "blink-free" light emission that is fully comparable with the light produced by dots made with more complex processes. The squashed dots emit spectrally narrow light
