A cyclic phosphate-based electrolyte for safe and high voltage lithium-ion batteries
In light of the ongoing shift toward renewable energy technologies and the growing number of Internet of Things (IoT) devices, researchers worldwide have been trying to develop batteries that can operate more efficiently and for longer periods of time. Lithium-ion...
A new transverse tunneling field-effect transistor
Researchers at the Chinese Academy of Sciences have recently fabricated a transverse tunneling field-effect transistor. This is a semiconductor device that can be used to amplify or switch electrical power or signals, operating through a phenomenon known as quantum...
LiftTiles: Actuator-based building blocks for shape-changing interfaces
Large-scale interfaces that change shape could be used to create interactive displays or environments that can be adapted to meet the needs human users. Despite their potential, creating these systems has so far proved challenging, as they can be expensive to build...
New organic-metal oxide transistors with high operational stability
Metal oxide thin-film transistors (TFTs), which are built by depositing thin films of an active metal oxide-based semiconducting material on a supporting substrate, have become widely used over the past few years, particularly in organic light-emitting diode displays....
A new design strategy to fabricate 2-D electronic devices using ultrathin dielectrics
2-D semiconductors could have very useful applications, particularly as channel materials for low-power transistors. These materials display very high mobility at extreme thicknesses, which makes them particularly promising alternatives to silicon in the fabrication...
A two-terminal floating-gate transistor for neuromorphic computing
Researchers at Technion and TowerJazz in Israel have recently built a low-power, two-terminal floating-gate transistor that could have useful applications in neuromorphic computing. This transistor, presented in a paper in Nature Electronics, was fabricated using...
Teaching AI agents navigation subroutines by feeding them videos
Researchers at UC Berkeley and Facebook AI Research have recently proposed a new approach that can enhance the navigation skills of machine learning models. Their method, presented in a paper pre-published on arXiv, allows models to acquire visuo-motor navigation...
Hourglass-shaped silicon photodiodes with an enhanced near-infrared photoresponse
Silicon photodiodes are semiconductor devices commonly used to detect visible light and measure its intensity, color and position. The fact that these devices are made of silicon has both advantages and disadvantages.
Flexible organic electrodes built using water-processed silver nanowires
Organic electronic devices, which are made of small molecules or polymers (i.e., substances composed primarily or completely of similar units bound together) are known to have several advantageous properties. In fact, organic electronics have relatively low production...
