Quantum computers, devices that exploit quantum phenomena to perform computations, could eventually help tackle complex computational problems faster and more efficiently than classical computers. These devices are commonly ...
In recent years, electronics engineers have been trying to broaden the pool of available semiconducting materials, to enable the development of a wider range of devices. One emerging class of semiconductors are amorphous ...
Organic semiconductors, a class of carbon-based materials with optical and electronic properties, are now commonly used to fabricate a variety of devices, including solar cells, light-emitting diodes and field-effect transistors. ...
(Phys.org)—For the first time, researchers have demonstrated a DNA nanomotor that can "walk" along a track with sustainable motion. The nanomotor also has the highest fuel efficiency for any type of walking nanomotor, or ...
(Phys.org)—Currently, all light-emitting diodes (LEDs) emit light of only one color, which is predefined during fabrication. So far, tuning the color of light produced by a single LED has never been realized, despite numerous ...
(Phys.org)—Constructing quantum computers and other quantum devices requires the ability to leverage quantum properties such as superposition and entanglement – but these effects are fragile and therefore hard to maintain. ...
(Phys.org)—The possibility that other universes exist beyond our own universe is tantalizing, but seems nearly impossible to test. Now a group of physicists has suggested that the Large Hadron Collider (LHC), the largest ...
Perfectly non-reflective objects, called blackbodies, produce blackbody radiation when at a uniform temperature. Although the properties of blackbody radiation depend on the blackbody's temperature, this radiation has always ...
(Phys.org)—Although quantum theory can explain three of the four forces in nature, scientists currently rely on general relativity to explain the fourth force, gravity. However, no one is quite sure of how gravity works ...
(Phys.org) -- The famous physicist Niels Bohr first conceived of the notion of quantum jumps, or quantum leaps, in 1913. Bohr understood quantum jumps as objective events in which an atom emits or absorbs a photon, causing ...
