In materials science, achromatic optical components can be designed with high transparency and low dispersion. Materials scientists have shown that although metals are highly opaque, densely packed arrays of metallic nanoparticles ...
Scientists have recently developed a light controlled nano-switch to lay groundwork for atomic device development in nanotechnology. They engineered the switches at the nanoscale in a first step toward fully integrated electronic ...
(Phys.org)—Researchers have found that a snowflake-like fractal design, in which the same pattern repeats at smaller and smaller scales, can increase graphene's inherently low optical absorption. The results lead to graphene ...
(Phys.org) —Although organic materials are often used as semiconductors, such as in organic LEDs and organic transistors, organic materials that have an electrical conductivity as high as that of metals are still very scarce. ...
(Phys.org) -- For the first time, physicists have experimentally demonstrated the interaction of two motionless light pulses. Because the stopped light pulses have a long interaction time, it increases the efficiency with ...
(PhysOrg.com) -- While the most common device for converting light into electricity may be photovoltaic (PV) solar cells, a variety of other devices can perform the same light-to-electricity conversion, such as solar-thermal ...
(PhysOrg.com) -- With the goal to enable small electronic devices to harvest their own energy, researchers have designed a device that can convert light and thermal energy into electricity. When exposed to visible light and/or ...
(PhysOrg.com) -- As one of the newest research areas today, the field of magnonics is attracting researchers for many reasons, not the least being its possible role in the development of transistor-less logic circuits. Information ...
(PhysOrg.com) -- As organic light-emitting diodes (OLEDs) are poised to go mainstream in the near future, scientists continue to explore new twists on the technology. Recently, researchers have fabricated a "liquid-OLED" ...
Scientists with the University of Chicago have demonstrated a way to create infrared light using colloidal quantum dots. The researchers said the method demonstrates great promise; the dots are already as efficient as existing ...
