Improving fabrication process of nano-structures for electronic devices

Wed, 2018-03-21 02:07
Researchers have found a more efficient fabricating process to produce semiconductors used in today's electronic devices. They also confirmed that materials other than silicon can be used successfully in the development process that could increase performance of electronic devices.

'Candy cane' polymer weave could power future functional fabrics and devices

Tue, 2018-03-20 18:14
If scientists are going to deliver on the promise of implantable artificial organs or clothing that dries itself, they'll first need to solve the problem of inflexible batteries that run out of juice too quickly. Today, researchers report that they've developed a new material by weaving two polymers together in a way that increases charge storage capacity.

Existence of new form of electronic matter

Thu, 2018-03-15 00:20
Researchers have produced a 'human scale' demonstration of a new phase of matter called quadrupole topological insulators that was recently predicted using theoretical physics. These are the first experimental findings to validate this theory.

Graphene flakes for future transistors

Thu, 2018-03-15 00:19
Tiny and very promising for possible applications in the field of nanoelectronics: they are the graphene nanoflakes. These hexagonal shaped nanostructures would allow to exploit quantum effects to modulate the current flow. Thanks to their intrinsic magnetic properties, they could also represent a significant step forward in the field of spintronics, which is based on the electron spin.

Researchers tap problematic e-waste surplus to recover high-quality polymers

Wed, 2018-03-14 20:39
Mixed-plastic electronics waste could be a valuable source of reusable polymers, a new study suggests. The team has developed the first energy-efficient and environmentally friendly process that separates mixed polymers so that they can be recycled into new, high-quality plastic products.

A milestone in petahertz electronics

Mon, 2018-03-12 23:45
In a semiconductor, electrons can be excited by absorbing laser light. Advances during the past decade enabled measuring this fundamental physical mechanism on timescales below a femtosecond. Now physicists have resolved the response of electrons in gallium arsenide at the attosecond timescale, and gained unexpected insights for future ultrafast opto-electronic devices with operation frequencies in the petahertz regime.

Riding the (quantum magnetic) wave

Mon, 2018-03-12 22:59
Scientists have shown that an organic-based magnet can carry waves of quantum mechanical magnetization, called magnons, and convert those waves to electrical signals. It's a breakthrough for the field of magnonics (electronic systems that use magnons instead of electrons) because magnons had previously been sent through inorganic materials that are more difficult to handle.

Flat gallium joins roster of new 2-D materials

Sat, 2018-03-10 03:36
Scientists have discovered a method to make atomically flat gallium that shows promise for nanoscale electronics.

New conductive coating may unlock biometric and wearable technology of the future

Sat, 2018-03-10 03:36
A team of researchers have developed a mechanically robust conductive coating that can maintain performance under heavy stretching and bending.

Metal-organic compounds produces new class of glass

Sat, 2018-03-10 00:53
Lightning and volcanos both produce glass, and humans have been making glass from silicon dioxide since prehistory. Industrialization brought us boron-based glasses, polymer glasses and metallic glasses, but now an international team of researchers has developed a new family of glass based on metals and organic compounds that stacks up to the original silica in glass-forming ability.

Breakthrough in circuit design makes electronics more resistant to damage and defects

Sat, 2018-03-10 00:32
A new article details an innovation that provides robust protection against circuitry damage that affects signal transmission.

Across the metal-molecule interface: Observing fluctuations on the single-molecule scale

Fri, 2018-03-09 21:17
Scientists have developed a technique for analyzing structural and electronic fluctuations on the single-molecule scale across the metal-molecule interface in an organic electronic device. This technique provides information that cannot be obtained using the conventional method, and it has important implications for devices such as organic solar cells.

Six-legged robots get closer to nature

Fri, 2018-03-09 20:24
A study has uncovered new ways of driving multi-legged robots by means of a two-level controller. The proposed controller uses a network of so-called non-linear oscillators that enables the generation of diverse gaits and postures, which are specified by only a few high-level parameters. The study inspires new research into how multi-legged robots can be controlled, including in the future using brain-computer interfaces.

A new class of two-dimensional materials

Fri, 2018-03-09 05:35
Scientists and engineers have developed a method to make new kinds of artificial "superlattices" -- materials composed of alternating layers of ultra-thin "two-dimensional" sheets, which are only one or a few atoms thick. Unlike current state-of-the art superlattices, in which alternating layers have similar atomic structures, and thus similar electronic properties, these alternating layers can have radically different structures, properties and functions, something not previously available.

Sewing atomic lattices seamlessly together

Fri, 2018-03-09 01:01
Scientists have revealed a technique to 'sew' two patches of crystals seamlessly together at the atomic level to create atomically-thin fabrics. (The smoother the seam between two materials, the more easily electrons flow across it -- essential for how well the electronic devices function.)

Nanostructures made of previously impossible material

Fri, 2018-03-09 00:03
One could think that mixing different materials is easy -- why not just melt them and pour them together? But if the goal is to create well-ordered crystals, things are more complicated. Scientists have now found a way to add large amounts of metal to semiconductor crystals, which changes their properties dramatically.

Heat switch developed for electronics

Thu, 2018-03-08 21:21
Researchers have developed new technology for switching heat flows 'on' or 'off'.

Direct observation of topology hidden inside materials

Topology hidden inside materials in the matter group called cerium monopnictides has been determined for the first time in the world.

Tue, 2018-03-06 23:48
Scientists have identified more than 1,000 materials with a particularly interesting 2-D structure.

Untapped gold mine is lost from end-of-life vehicles

Tue, 2018-03-06 20:01
Vast quantities of scarce metals are being lost from Europe's urban mine of vehicles, including 20 tonnes of gold each year – and the proportion of critical metals in vehicles is continuing to increase. A database is now being published that charts the metals and facilitates recycling.
