New nanoscale light-emitting diode is thousands of times more energy efficient that laser-based devices and ultrafast; could transform computer data transmission at the chip level A team at Stanford's School of Engineering has demonstrated an ultrafast nanoscale light emitting diode (LED) that is orders of magnitude lower in power consumption than today's laser-based systems and able to transmit data at 10 billion bits per second. The researchers say it is a major step forward in providing...

A robust new architecture enables optimization for quantum-dot displays By nestling quantum dots in an insulating egg-crate structure, researchers at the Harvard School of Engineering and Applied Sciences (SEAS) have demonstrated a robust new architecture for quantum-dot light-emitting devices (QD-LEDs). Quantum dots are very tiny crystals that glow with bright, rich colors when stimulated by an electric current. QD-LEDs are expected to find applications in television and computer...

Researchers at Yale University are studying how two types of nanoscale structures on the feathers of birds produce brilliant and distinctive colors. The researchers are hoping that by borrowing these nanoscale tricks from nature they will be able to produce new types of lasers–ones that can assemble themselves by natural processes. The team will present their findings at the Optical Society's (OSA) Annual Meeting, Frontiers in Optics (FiO) 2011, taking place in San Jose, Calif. next...

A nanoscale game of "now you see it, now you don't" may contribute to the creation of metamaterials with useful optical properties that can be actively controlled, according to scientists at Rice University. A Rice laboratory led by chemist Stephan Link has discovered a way to use liquid crystals to control light scattered from gold nanorods. The researchers use voltage to sensitively manipulate the alignment of liquid crystal molecules that alternately block and reveal light from the...

Researchers of the Chemical Engineering department and the Kavli institute of TU Delft have demonstrated that electrons can move freely in layers of linked semiconductor nanoparticles under the influence of light. This new knowledge will be very useful for the development of cheap and efficient quantum dot solar cells. The researchers published their findings on Sunday 25 September on the website of the scientific journal Nature Nanotechnology. Cheap and efficient The current...

RUB scientists succeeded in moving individual electrons, report in 'Nature' Physicists at the RUB, working in collaboration with researchers from Grenoble and Tokyo, have succeeded in taking a decisive step towards the development of more powerful computers. They were able to define two little quantum dots (QDs), occupied with electrons, in a semiconductor and to select a single electron from one of them using a sound wave, and then to transport it to the neighboring QD. A single electron...

Researchers from the University of Toronto (U of T), the King Abdullah University of Science & Technology (KAUST) and Pennsylvania State University (Penn State) have created the most efficient solar cell ever made based on collodial-quatum-dots (CQD). The discovery is reported in the latest issue of Nature Materials. Quantum dots are nanoscale semiconductors that capture light and convert it into an energy source. Because of their small scale, the dots can be sprayed on to flexible...
