Nano-sandwiching improves heat transfer, prevents overheating in nanoelectronics

Thu, 2018-09-13 00:14
Sandwiching two-dimensional materials used in nanoelectronic devices between their three-dimensional silicon bases and an ultrathin layer of aluminum oxide can significantly reduce the risk of component failure due to overheating, according to a new study published in the journal of Advanced Materials led by researchers at the University of Illinois at Chicago College of Engineering.

Bismuth shows novel conducting properties

Wed, 2018-09-12 19:20
Scientists have discovered a new class of materials: higher-order topological insulators. Theoretical physicists first predicted the existence of these insulators with conducting properties on the edges of crystals rather than on their surface and their characteristic ability to conduct electricity without dissipation. Now, these novel properties are demonstrated experimentally in bismuth.

An international team has synthesized a novel nano material with electrical and magnetic properties making it suitable for future quantum computers and other applications in electronics.

Diamond dust enables low-cost, high-efficiency magnetic field detection

Mon, 2018-09-10 23:54
Engineers have created a device that dramatically reduces the energy needed to power magnetic field detectors, which could revolutionize how we measure the magnetic fields that flow through our electronics, our planet, and even our bodies. The researchers found a new way to excite tiny diamonds with microwaves using 1,000 times less power, making it feasible to create magnetic-sensing devices that can fit into electronics like cell phones.

Graphene enables clock rates in the terahertz range

Mon, 2018-09-10 20:42
Graphene is considered a promising candidate for the nanoelectronics of the future. In theory, it should allow clock rates up to a thousand times faster than today's silicon-based electronics. Scientists have now shown that graphene can actually convert electronic signals with frequencies in the gigahertz range extremely efficiently into signals with several times higher frequency.

Tue, 2018-09-04 20:02
Researchers have successfully fabricated a lithium trivanadate (LVO) cathode thick film on a garnet-type oxide solid electrolyte using the aerosol deposition method. The LVO cathode thick-film fabricated on the solid electrolyte showed a large reversible charge and discharge capacity as high as 300 mAh/g and a good cycling stability at 100 ºC. This finding may contribute to the realization of highly safe and chemically stable oxide-based all-solid-state lithium batteries.

A team of researchers has, for the first time, fully 3D printed an array of light receptors on a hemispherical surface. This discovery marks a significant step toward creating a 'bionic eye' that could someday help blind people see or sighted people see better.

New sensor could help doctors monitor patient progress from a distance

Tue, 2018-08-28 21:18
A self-powered sensor could allow doctors to remotely monitor the recovery of surgical patients. The small, tube-like device is designed to be fitted to braces after joint surgery to wirelessly send information to computers, smartphones or smartwatches to track range of motion and other indicators of improvement.

Tue, 2018-08-28 20:10
A method can produce large quantities of pristine single-walled carbon nanotubes in select shades of the rainbow. The secret is a fine-tuned fabrication process -- and a small dose of carbon dioxide. The films could find applications in touch screen technologies or as coating agents for new types of solar cells.

Mon, 2018-08-27 19:34
The existing surface termination technique using hydrogen to stabilize the diamond's structure for application in electronic power devices results in two-dimensional hole gas layers (2DHG). Attempting to remove these layers using oxygen-termination roughens the diamond surface and leads to degradation of the device performance. To overcome this, researchers removed 2DHG from diamond using water vapor annealing and maintained an atomically flat surface.
