Many regions are experiencing a critical shortage of ventilators as COVID-19 infections continue to rise and hospital demand exceeds supply.
Light from Stretchable Sheets of Atoms for Quantum Technologies
The researchers say their results, using an atomically thin material, hexagonal boron nitride, constitute a significant step forward in understanding light-matter interactions of quantum systems in 2D materials, and the journey towards scalable on-chip devices for quantum technologies. The study is published in Advanced Materials.
Shedding Light on Dark Traps
A multi-institutional collaboration, co-led by scientists at the University of Cambridge and Okinawa Institute of Science and Technology Graduate University (OIST), has discovered the source of efficiency-limiting defects in potential materials for next generation solar cells and flexible LEDs.
Untwisting Plastics for Charging Internet-of-Things Devices
Untwisting chains of atoms within a plastic polymer improves its ability to conduct electricity, according to a report by researchers, led by Nagoya University applied physicist Hisaaki Tanaka, in the journal Science Advances. The insight could help accelerate the development of wearable power sources for a vast number of Internet-of-things devices.
Transphorm Introduces SuperGaN Power FETs with Launch of Gen IV GaN Platform
Transphorm Inc.— the leader in the design and manufacturing of the highest reliability and first JEDEC- and AEC-Q101 qualified high voltage gallium nitride (GaN) power semiconductors — today announced availability of its Gen IV GaN platform. Transphorm’s latest technology offers notable advancements in performance, designability, and cost when compared to its previous GaN generations. Related, Transphorm also announced today that Gen IV and future platform generations will be called SuperGaN technologies.
Industry’s First DisplayPort 2.0 Active Switch Introduced by Diodes Incorporated
Diodes Incorporated (Nasdaq: DIOD) today announced the industry’s first DisplayPort™ 2.0 (UHBR10) compliant 4-lane, 2:1 active switch with multiplexer and ReDriver™, the PI3DPX8121. The device joins the company’s portfolio of DisplayPort switching and signal conditioning solutions engineered to meet the design needs of PCs, monitors, set-top boxes, and other AV equipment.
Breaking the Size and Speed Limit of Modulators: The Workhorses of the Internet
Researchers developed and demonstrated for the first time a silicon-based electro-optical modulator that is smaller, as fast as and more efficient than state-of-the-art technologies. By adding indium tin oxide (ITO) – a transparent conductive oxide found in touchscreen displays and solar cells – to a silicon photonic chip platform, the researchers were able to create a compact device 1 micrometer in size and able to yield gigahertz-fast, or 1 billion times per second, signal modulation.
The Power of Light
As COVID-19 continues to ravage global populations, the world is singularly focused on finding ways to battle the novel coronavirus. That includes the UC Santa Barbara’s Solid State Lighting & Energy Electronics Center (SSLEEC) and member companies. Researchers there are developing ultraviolet LEDs that have the ability to decontaminate surfaces — and potentially air and water — that have come in contact with the SARS-CoV-2 virus.
NREL Six-Junction Solar Cell Sets Two World Records for Efficiency
Scientists at the National Renewable Energy Laboratory (NREL) have fabricated a solar cell with an efficiency of nearly 50%. The six-junction solar cell now holds the world record for the highest solar conversion efficiency at 47.1%, which was measured under concentrated illumination. A variation of the same cell also set the efficiency record under one-sun illumination at 39.2%.
