Light-Emitting V-Pits: An Alternative Approach toward Luminescent Indium-Rich InGaN Quantum Dots


Abstract: "Realization of fully solid-state white light emitting devices requires high efficiency blue, green, and red emitters. However, challenges remain in boosting the low quantum efficiency of long wavelength group-III-nitride light emitters through conventional quantum well growth. Here, we demonstrate a new direct metal–organic chemical vapor deposition approach to grow In-rich InGa... » read more

Magnetic glue Nanyang Technological University (NTU) Singapore has developed a new magnetic-activated glue technology. Conventional glue or adhesives involve epoxy and related materials. These adhesives are used to bond plastics, ceramics and wood. The adhesives are bonded and cured using moisture, heat or light. The curing temperatures range from room temperature to 80 degrees Celsius. ... » read more

Cooling sensors with lasers Researchers at the University of Washington developed a way to cool a solid semiconductor sensor component with an infrared laser. The laser was able to cool the solid semiconductor by at least 20 degrees C, or 36 F, below room temperature. The device uses a cantilever, similar to a diving board, that can oscillate in response to thermal energy at room temperatur... » read more

Autonomous microscopes FLEET, also known as the ARC Centre of Excellence in Future Low-Energy Electronics Technologies, has developed an autonomous scanning probe microscopy (SPM) technology. SPM is an instrument that makes use of an atomically sharp probe. The probe is placed in close proximity above the surface of a sample. With the probe, the SPM forms images of the surface of the sample... » read more

Quantum communications chip Researchers at Nanyang Technological University, Australian National University, A∗STAR, University of Science and Technology of China, Singapore University of Technology and Design, Sun Yat-sen University, Beijing University of Posts and Telecommunications, and National University of Singapore built an integrated silicon photonic chip capable of performing quantu... » read more

Magnetic Memories Reach For Center Stage


Wearable heart rate sensors. Networked smoke detectors. Smart lighting. Smart doorbells. While desktop computers and even smartphones are powerful standalone tools, Internet of Things devices share a need to collect data from the environment, store it, and transmit it to some other device for action or further analysis. In many systems, data storage and working memory account for the majorit... » read more

Silicon spintronics Engineers at the University of California, Riverside, developed new methods to detect signals from spintronic components made of low-cost metals and silicon. Spintronic devices generate little heat, use relatively minuscule amounts of electricity, and would require no energy to maintain data in memory. However, previously developed spintronic devices depend on complex struc... » read more

Novel quantum computing architecture invented University of New South Wales researchers have invented what they say is a radical new architecture for quantum computing, based on ‘flip-flop qubits,’ that promises to make the large-scale manufacture of quantum chips dramatically easier. [caption id="attachment_319384" align="alignnone" width="300"] Artist's impression of flip-flop qubit e... » read more
