A new study describes an innovative method to make stacks of semiconductors just a few atoms thick. The technique offers scientists and engineers a simple, cost-effective method to make thin, uniform layers of these materials, which could expand capabilities for devices from solar cells to cell phones.
Researchers use interference in the motion of a micrometer-size drum to route microwave signals in a single direction.
Scarce metals are found in a wide range of everyday objects around us. They are complicated to extract, difficult to recycle and so rare that several of them have become "conflict minerals" which can promote conflicts and oppression. New research shows that there are potential technology-based solutions that can replace many of the metals with carbon nanomaterials, such as graphene.
Today, electrical bistable devices are the foundation of digital electronics, serving as building blocks of switches, logic gates and memories in computer systems. However, the bandwidth of these electronic computers is limited by the signal delay of time constants important to electronic logic operations. In an attempt to mitigate these problems, scientists have considered the development of an optical digital computer, and one team has gone so far as to demonstrate the optical and electrical bistability for switching in a single transistor.
Researchers produced the first 2-D field-effect transistor (FET) made of a single material.
Researchers have just shown the first new type of quantum oscillation to be reported for thirty years. It is the first of its kind to be present at high temperature and on the mesoscale and sheds light on the Hofstadter butterfly phenomenon.
A group of researchers successfully demonstrated record-small electrically pumped micro-lasers epitaxially grown on industry standard (001) silicon substrates in a recent study. The thresholds and footprints are orders of magnitude smaller than those previously reported lasers epitaxially grown on Si.
In a world first, researchers have stored photonic information on a microchip as an acoustic wave. This allows precious extra time to store, process and then redistribute the data without relying on electronics, which produce excess heat. Such a hybrid chip could have a huge impact in cloud computing and telecommunication centers, which are overheating as we churn through data on our phones.
As electronic devices get smaller, their ability to provide precise, chip-based sensing of dynamic physical properties such as motion become challenging to develop. An international group of researchers have put a literal twist on this challenge, demonstrating a new nanoscale optomechanical resonator that can detect torsional motion at near state-of-the-art sensitivity. Their resonator, into which they couple light, also demonstrates torsional frequency mixing, a novel ability to impact optical energies using mechanical motions.
Researchers are rolling out a new manufacturing process and chip design for silicon carbide (SiC) power devices, which can be used to more efficiently regulate power in technologies that use electronics. The process -- called PRESiCE -- was developed to make it easier for companies to enter the SiC marketplace and develop new products.
A team of researchers from the University of Houston has reported a breakthrough in stretchable electronics that can serve as an artificial skin, allowing a robotic hand to sense the difference between hot and cold, while also offering advantages for a wide range of biomedical devices.
Researchers have created a printable structure that begins to fold itself up as soon as it's peeled off the printing platform.
As demand grows for more versatile, advanced robotics and other technologies, the need for components that can enable these applications also increases. Producing such components en masse has been a major challenge. But now, researchers report that they have developed a way to help meet this need by printing electronics that can fold themselves into a desired shape.
Experts have designed a flexible and organic alternative to the rigid batteries that power up medical implants.
Chemical and electrical engineers team up to create a new breed of microdevices for medical diagnostics.
Researchers have established new findings on the properties of two-dimensional molybdenum disulfide, a widely studied semiconductor of the future.
Men build dams and huge turbines to turn the energy of waterfalls and tides into electricity. To produce hydropower on a much smaller scale, scientists have now developed a lightweight power generator based on carbon nanotube fibers suitable to convert even the energy of flowing blood in blood vessels into electricity.
A stretchy miracle material has been discovered that could be used to create highly resistant smart devices and scratch-proof paint for cars, report investigators.
Researchers have reported a new type of electronic device that can be triggered to dissolve through exposure to water molecules in the atmosphere. The work holds promise for eco-friendly disposable personal electronics and biomedical devices that dissolve within the body.
Scientists have developed a new tool for imaging life at the nanoscale that will provide new insights into the role of transition metal ions such as copper in neurodegenerative diseases.
