Shedding light on why blue LEDs are so tricky to make
Scientists at University College London, in collaboration with groups at the University of Bath and the Daresbury Laboratory, have uncovered the mystery of why blue light-emitting diodes (LEDs) are so difficult to make, by ...
High-resolution patterns of quantum dots with e-jet printing
FingerShadow is proposed as screen power-saving technique
Researchers advance toward hybrid spintronic computer chips
Researchers here have created the first electronic circuit to merge traditional inorganic semiconductors with organic "spintronics" devices that utilize the spin of electrons to read, write and manipulate data.
Physicists observe 'campfire effect' in blinking nanorod semiconductors
When semiconductor nanorods are exposed to light, they blink in a seemingly random pattern. By clustering nanorods together, physicists at the University of Pennsylvania have shown that their combined "on" time is increased ...
Quantum-dot LED screens may soon rival OLEDs and LCDs
Visualizing interacting electrons in a molecule
Scientists at Aalto University and the University of Zurich have succeeded in directly imaging how electrons interact within a single molecule.
OLED experts to advance improved production techniques
Back in May, Steven Shankland in CNET said that, for the lighting business, "the next technology is coming: OLED (organic light-emitting diode) lighting. It replaces the small, bright dots of LEDs with sheets of light that aren't so piercingly bright." Now MIT Technolog ...
Atomically thin material opens door for integrated nanophotonic circuits
A new combination of materials can efficiently guide electricity and light along the same tiny wire, a finding that could be a step towards building computer chips capable of transporting digital information ...
NJIT researchers invent flexible battery made from carbon nanotubes
Researchers at NJIT have developed a flexible battery made with carbon nanotubes that could potentially power electronic devices with flexible displays.
Discovery could yield more efficient portable electronics, solar cells
By figuring out how to precisely order the molecules that make up what scientists call organic glass—the materials at the heart of some electronic displays, light-emitting diodes and solar cells—a team ...
LG unveils curved-screen smartphone
LG Electronics unveiled Monday a curved-screen smartphone, taking on rival Samsung in a niche market seen as a first step on the road to fully flexible products.
Ceiling lights in Minn. send coded Internet data
(AP) -- Flickering ceiling lights are usually a nuisance, but in city offices in St. Cloud, they will actually be a pathway to the Internet.
Novel LEDs pave the way to cheaper displays
Researchers from the universities of Bonn and Regensburg have developed a novel type of organic light-emitting diode (OLED). These lights are suitable for the design of particularly energy-efficient cheap ...
