Electronic Diodes Demonstrate Performance Beyond 5G
Applications include high-speed communications, networking, and sensing.
Researchers at Linköping University, together with colleagues in China, have developed a tiny unit that is both an optical transmitter and a receiver.
This work potentially opens the door to advances like more energy-efficient electronic devices.
The AI system can help shorten the time required for 2D material-based electronics to be ready for consumer devices.
These thin films hold great promise for solar cells and LEDs.
This method will enable safer fluorescent light recycling.

NASA Langley Research Center has developed a double-sided Si(Ge)/ Sapphire/III-Nitride hybrid structure. This technology uses both sides of a sapphire wafer to build device...

3D Printing of Flexible Circuits

A process was developed for 3D printing that can be used to produce transparent and mechanically flexible electronic circuits. The electronics consist of a mesh of silver nanowires that can be printed in suspension and embedded in various flexible and transparent plastics (polymers). This technology can enable...

Self-Powered, Washable, Wearable Displays

Clothing usually is formed with textiles and has to be both wearable and washable for daily use; however, smart clothing has had a problem with its power sources and moisture permeability, which causes the devices to malfunction. To solve this problem, a textile-based, wearable display module technology...

Researchers devised a method in which running a light emitting diode (LED) with electrodes reversed was able to cool another device nanometers away. They harnessed the chemical potential...

One of the frontiers of medical diagnostics is the race for more sensitive blood tests. The ability to detect extremely rare proteins could make a life-saving difference for many...

The combination of conductive polymers on nanostructures was demonstrated as suited to creating electronic displays as thin as paper. The “paper” is similar to the Kindle tablet. It...

Sponsored by the Office of Naval Research's (ONR) TechSolutions program, the Flashing Light to Text Converter (FLTC) features a camera that can be mounted atop a signal...

An optical setup developed by researchers at Sandia's Combustion Research Facility and the Technical University of Denmark can now quantify the formation of soot — particulate matter consisting...

Single-Crystal SiGe/Sapphire Epitaxy

NASA's Langley Research Center has developed a new low-temperature method of SiGe/sapphire growth that produces the same single-crystal films with much less thermal loading effort to the substrate. This eliminates the time-consuming and costly high heating, long thermal soak times, and interfacial Si layer....

One current method to build a semiconductor superlattice — materials comprised of alternating layers of ultra-thin, two-dimensional sheets only one or a...

When hit with light, semiconductors (materials that have an electrical resistance in between that of metals and insulators) generate an electric current....

Optical fibers have been traditionally produced by making a cylindrical object called a preform — essentially, a scaled-up model of the fiber — and then heating it. Softened...

Computer processors have continued to shrink down to nanometer sizes where there can be billions of transistors on a single chip. This phenomenon is described under Moore's Law, which...

Positional sensors have applications where a very accurate measurement of position is needed over a limited range. One example of such an application is in manipulation of a...

A driverless car is making its way through a winding neighborhood street, about to make a sharp turn onto a road where a child’s ball has just rolled. Although no person in the car can see that ball, the...

Crew time on the International Space Station (ISS) is extremely limited for any operations on science payloads. Autonomous science experiments in small, self-contained, cubical payloads are highly desirable...

Wireless Charging of Moving Electric Vehicles

If electric cars could recharge while driving down a highway, it would virtually eliminate concerns about their range and lower their cost, perhaps making electricity the standard fuel for vehicles. Researchers have wirelessly transmitted electricity to a nearby moving object, which could advance...

Machine Vision System

A number of instruments have been built to obtain range images — a two-dimensional array of numbers that gives the depth of a scene along many directions from a central point in the instrument. Instead of measuring...

High-Performance Photocatalytic Oxidation Reactor System

As crewed space missions extend beyond low Earth orbit, the need to reliably recover potable water is critical. Aboard the International Space Station (ISS), the water is recycled from cabin humidity condensate, urine distillate, and hygiene wash wastes. In spacecraft cabin air...

High-tech specks called quantum dots could bring brighter, more vibrant color to mass market TVs, tablets, phones and other displays. A new technology called 3M quantum dot enhancement...

Scientists at the University of Washington have developed what they believe is the thinnest-possible semiconductor, a new class of nanoscale materials made in sheets only three...

A team of researchers has demonstrated that atomic force microscope (AFM) probe tips made from its near-perfect gallium nitride nanowires are superior in many respects to standard silicon or...

Researchers from North Carolina State University have developed a new processing technique that makes light emitting diodes (LEDs) brighter and more resilient by coating the semiconductor...
