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)—Global demand for data storage is constantly increasing, driven by new technologies such as Big Data and the Internet of Things, as well as personal and enterprise storage. The hard disk drives that currently ...
Electronic devices such as transistors are getting smaller and will soon hit the limits of conventional performance based on electrical currents.

Ultra-low-loss metal films with high-quality single crystals are in demand as the perfect surface for nanophotonics and quantum information processing applications. Silver is by far the most preferred material due to low-loss ...
Physicists at UC San Diego have developed a new way to control the transport of electrical currents through high-temperature superconductors—materials discovered nearly 30 years ago that lose all resistance to electricity ...

Scientists and Engineers have used surface-emitting semiconductor lasers in data communications, for sensing, in FaceID and within augmented reality glasses. In a new report, Yong-Ho Ra and a research team in the departments ...
One of the most enduring "Holy Grail" experiments in science has been attempts to directly observe atomic motions during structural changes. This prospect underpins the entire field of chemistry because a chemical process ...
