Nanostructure boosts stability of organic thin-film transistors

Sat, 2018-01-13 01:42
A nanostructured gate dielectric may have addressed the most significant obstacle to expanding the use of organic semiconductors for thin-film transistors. The structure, composed of a fluoropolymer layer followed by a nanolaminate made from two metal oxide materials, serves as gate dielectric and protects the organic semiconductor - which had previously been vulnerable to damage from the ambient environment.

Breaking bad metals with neutrons

Fri, 2018-01-12 00:46
By combining the latest developments in neutron scattering and theory, researchers are close to predicting phenomena like superconductivity and magnetism in strongly correlated electron systems. It is likely that the next advances in superconductivity and magnetism will come from such systems, but they might also be used in completely new ways such as quantum computing.

A major step forward in organic electronics

Thu, 2018-01-11 22:23
Researchers have developed the world's first complementary electrochemical logic circuits that can function stably for long periods in water. This is a highly significant breakthrough in the development of bioelectronics.

New oxide and semiconductor combination builds new device potential

Wed, 2018-01-10 21:59
Researchers have now grown a 2DEG system on gallium arsenide, a semiconductor that's efficient in absorbing and emitting light. This development is promising for new electronic devices that interact with light, such as new kinds of transistors, superconducting switches and gas sensors.

Physicists build muscle for shape-changing, cell-sized robots

Thu, 2018-01-04 02:31
Robotics experts have made a robot exoskeleton that can rapidly change its shape upon sensing chemical or thermal changes in its environment. And, they claim, these microscale machines -- equipped with electronic, photonic and chemical payloads -- could become a powerful platform for robotics at the size scale of biological microorganisms.

Carbon nanotubes devices may have a limit to how 'nano' they can be

Wed, 2018-01-03 20:41
Carbon nanotubes bound for electronics not only need to be as clean as possible to maximize their utility in next-generation nanoscale devices, but contact effects may limit how small a nano device can be, according to researchers.

'Quantum radio' may aid communications and mapping indoors, underground and underwater

Wed, 2018-01-03 02:02
Researchers have demonstrated that quantum physics might enable communications and mapping in locations where GPS and ordinary cellphones and radios don't work reliably or even at all, such as indoors, in urban canyons, underwater and underground.

Exploring electrolysis for energy storage

Tue, 2018-01-02 22:12
A research team developed a flow-type polymer electrolyte cell for power storage. The cell reduces oxalic acid (OX) to glycolic acid, which has a higher volumetric energy-storage capacity than hydrogen gas. Newly fabricated TiO2 cathode enhanced the speed and efficiency of OX reduction. This competitive energy-storage device could be used to balance out the fluctuations in renewable power supplies.

Electronically-smooth '3-D graphene': A bright future for trisodium bismuthide

Sun, 2017-12-24 00:18
Researchers have found that the topological material trisodium bismuthide (Na3Bi) can be manufactured to be as 'electronically smooth' as the highest-quality graphene-based alternative, while maintaining graphene's high electron mobility.

Now entering, lithium niobate valley

Fri, 2017-12-22 00:06
Lithium niobate is already one of the most widely used optical materials, well-known for its electro-optic properties but it is notoriously difficult to fabricate high-quality devices on a small scale using lithium niobate, an obstacle that has so far ruled out practical integrated, on-chip applications. Now, researchers have developed a technique to fabricate high-performance optical microstructures using lithium niobate, opening the door to ultra-efficient integrated photonic circuits, quantum photonics, microwave-to-optical conversion and more.

Thu, 2017-12-21 20:44
Highly desired in the petrochemical industry, but generally unwanted in electronics manufacture, defects in MoS2 influence the properties and utility of this material. Analysis of atomically thin MoS2 reveals how defects behave and relate to MoS2's anomalies.

Metal printing offers low-cost way to make flexible, stretchable electronics

Wed, 2017-12-20 22:50
Researchers have developed a new technique for directly printing metal circuits, creating flexible, stretchable electronics. The technique can use multiple metals and substrates and is compatible with existing manufacturing systems that employ direct printing technologies.

Acoustic device makes piezoelectrics sing to a different tune

Wed, 2017-12-20 08:24
In today's 'internet of things,' devices connect primarily over short ranges at high speeds, an environment in which surface acoustic wave devices have shown promise for years. To obtain faster speeds, however, SAW devices need to operate at higher frequencies, limiting output power and overall performance. Researchers have demonstrated a new device that can achieve frequencies six times higher than most current devices. Their results are published this week in Applied Physics Letters.

Researchers have chemically imprinted polymer particles with DNA strands -- a technique that could lead to new materials for applications ranging from biomedicine to the promising field of 'soft robotics.'

Westminster Abbey windows help shine light on glass myth

Mon, 2017-12-18 23:42
Gazing through the stained-glass windows of London's Westminster Abbey can evoke memories as diverse and vivid as the windows themselves, but to a glass researcher, the windows sparked a quest to better understand the science behind the iconic portals to history.

A new theory to describe widely used material
