A quantum magnet with a topological twist

Fri, 2019-02-22 23:49
Researchers probed a special kind of magnet containing atoms arranged in a pattern called a kagome lattice, which takes its name from a Japanese basket. They found that electrons in this material exhibit exotic behaviors that could be exploited for futuristic applications -- and that under a high magnetic field some electrons in this material act like an upside-down magnet.

Magnetization reversal achieved at room temperature using only an electric field

Fri, 2019-02-22 20:42
Scientists have achieved magnetization reversal in cobalt-substituted bismuth ferrite by applying only an electric field. Such an effect had been sought after for over a decade in order to make new types of low-power-consumption magnetic memory devices.

Expanding the use of silicon in batteries, by preventing electrodes from expanding

Thu, 2019-02-21 23:33
Silicon anodes are generally viewed as the next development in lithium-ion battery technology. Silicon's ability to absorb more charge translates to longer battery life and smaller batteries, if researchers can check the physical expansion of the silicon that comes with charging. Research suggests that adding MXene ink to the silicon electrode-making process would do just that.

Breakthrough in the search for graphene-based electronics

Tue, 2019-02-19 23:57
A team of researchers from Denmark has solved one of the biggest challenges in making effective nanoelectronics based on graphene.

Digital phase-locked loop achieves a power consumption of 0.265 mW

Tue, 2019-02-19 21:46
Scientists have developed an advanced phase-locked loop (PLL) frequency synthesizer that can drastically cut power consumption. This digital PLL could be an attractive building block for Bluetooth Low Energy (BLE) and other wireless technologies to support a wide range of Internet of Things (IoT) applications.

Exotic spiraling electrons discovered by physicists

Tue, 2019-02-19 02:02
Physicists have discovered an exotic form of electrons that spin like planets and could lead to advances in lighting, solar cells, lasers and electronic displays. It's called a 'chiral surface exciton,' and it consists of particles and anti-particles bound together and swirling around each other on the surface of solids, according to a new study.

Better red than dread: Barrier keeps batteries safe

Fri, 2019-02-15 02:01
A layer of red phosphorus in rechargeable lithium metal batteries can signal when damaging dendrites threaten to create a short circuit. The strategy, which does not require a third electrode, could help bring more powerful lithium metal batteries to market.

Chemical data mining boosts search for new organic semiconductors

Thu, 2019-02-14 22:25
Organic semiconductors are lightweight, flexible and easy to manufacture. But they often fail to meet expectations regarding efficiency and stability. Researchers are now deploying data mining approaches to identify promising organic compounds for the electronics of the future.

Sustainable electronics manufacturing breakthrough

Thu, 2019-02-14 03:53
Researchers are developing an eco-friendly, 3D printable solution for producing wireless Internet-of-Things (IoT) sensors that can be used and disposed of without contaminating the environment.

High-performance quantum dot mode-locked laser on silicon

Wed, 2019-02-13 23:52
Ten years into the future. That's about how far an electrical and computer engineering professor and his research team are reaching with the recent development of their mode-locked quantum dot lasers on silicon. It's technology that not only can massively increase the data transmission capacity of data centers, telecommunications companies and network hardware products to come, but do so with high stability, low noise and the energy efficiency of silicon photonics.

Customized mix of materials for three-dimensional micro- and nanostructures

Wed, 2019-02-13 20:34
Three-dimensional structures on the micrometer and nanometer scales have a great potential for many applications. An efficient and precise process to print such structures from different materials has now been presented: researchers have integrated a microfluidic chamber into a 3D laser lithography device. Then, they used this system to produce multi-colored, fluorescent security features to protect banknotes, documents, and branded products against counterfeiting.

Laser physics: Transformation through light

Tue, 2019-02-12 22:31
Laser physicists have taken snapshots of how C60 carbon molecules react to extremely short pulses of intense infrared light.

Using artificial intelligence to engineer materials' properties

Tue, 2019-02-12 03:10
New system of 'strain engineering' can change a material's optical, electrical, and thermal properties.

Engineers develop room temperature, two-dimensional platform for quantum technology

Tue, 2019-02-12 00:30
Researchers have now demonstrated a new hardware platform based on isolated electron spins in a two-dimensional material. The electrons are trapped by defects in sheets of hexagonal boron nitride, a one-atom-thick semiconductor material, and the researchers were able to optically detect the system's quantum states.

Chirality of Weyl fermions

Tue, 2019-02-12 00:30
Quasiparticles that behave like massless fermions, known as Weyl fermions, have been in recent years at the center of a string of exciting findings in condensed matter physics. Physicists now report experiments in which they got a handle on one of the defining properties of Weyl fermions -- their chirality.

Mon, 2019-02-11 23:44
Scientists have built a photonic integrated, compact, and portable soliton microcomb source. The device is less than 1 cm3 in size, and is driven by an on-chip indium phosphide laser consuming less than 1 Watt of electrical power. It can be used in LIDAR, data center interconnects, and even satellites.
