We will soon live in an era where perhaps more than 80 per cent of computer processors' transistors must be powered off and 'remain dark' at any time to prevent the chip from overheating. Researchers are racing against time to find smart solutions to the rapidly advancing era of ?dark silicon?.
The ability to generate single photons on demand holds the key to realization of such a communication scheme. By demonstrating that incorporation of pristine single-walled carbon nanotubes into a silicon dioxide matrix could lead to creation of solitary oxygen dopant state capable of fluctuation-free, room-temperature single photon emission, researchers revealed a new path toward on-demand single photon generation.
This research provides immediate insights into lithium-ion battery performance and far-reaching implications for the design of new materials for energy generation and storage, next gen computing, green technologies, and other areas.
With the help of a semiconductor quantum dot, physicists have developed a new type of light source that emits single photons. For the first time, the researchers have managed to create a stream of identical photons.
An international team of scientists has developed what may be the first one-step process for making seamless carbon-based nanomaterials that possess superior thermal, electrical and mechanical properties in three dimensions.
Researchers report on advances in three key areas - flexible electrodes, flexible encapsulation methods, and flexible substrates - that make commercial use of flexible lighting technology more feasible and closer to implementation.
Using computational and experimental methods, researchers at Caltech have developed a technique for creating so-called protein-DNA nanowires - a hybrid biomaterial that could have important applications.
A new study presents evidence for a long-sought phenomenon - first theorized in the 1960s and predicted to be found in crystals in 1983 - called the 'chiral anomaly' in a metallic compound of sodium and bismuth. The additional finding of an increase in conductivity in the material may suggest ways to improve electrical conductance and minimize energy consumption in future electronic devices.
A new could offer a simple way to improve the efficiency of electronic devices such as light-emitting diodes, optical fibers and solar cells. It also could have important theoretical implications for understanding the still surprisingly mysterious materials called glasses.
We invariably imagine electronic devices to be made from silicon chips, with which computers store and process information as binary digits (zeros and ones) represented by tiny electrical charges. But it need not be this way: among the alternatives to silicon are organic mediums such as DNA.
