A key objective in the electronics engineering field is to develop transistors and other electronic components that are increasingly compact and efficient, utilizing readily available processes and materials. Among the transistors ...
Spintronic devices, a class of architectures that can store or transfer information by leveraging the intrinsic spin of electrons, have been found to be highly promising, both in terms of speed and efficiency. So far, however, ...
We might imagine that electric current flows as a smooth, even stream of electrons through our electronics devices, but at the quantum scale the flow of electric current might be more accurately pictured as a bubbling brook ...
(Phys.org)—Capacitors are widely used in electrical circuits to store small amounts of energy, but have never been used for large-scale energy storage. Now researchers from Japan have shown that the right combination of ...
Invisibility cloaks can make objects invisible not just to light in the visible part of the spectrum, but to many other physical excitations. These include acoustic waves, matter waves, heat flux, and infrared or ultraviolet ...
(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) —It's a first: researchers have built the first artificial-heart-like pump that is powered by microbial fuel cells fed on human urine. But instead of being used as a prosthetic device for human patients suffering ...
(Phys.org) —Using an ink containing tiny graphene flakes, scientists have inkjet-printed graphene patterns that can be used for printing finely detailed, highly conductive electrodes. Although inkjet-printed graphene has ...
(Phys.org)—For many electronic devices, colder is better. At low temperatures, electronic devices such as sensors and detectors operate with a higher efficiency and better overall performance than they do at room temperature. ...
(Phys.org)—While most of today's electric vehicles rely on batteries to store energy, supercapacitors have enjoyed significant improvements that have made them serious competitors to batteries. Batteries traditionally have ...
