Blue phosphorus, an atomically thin synthetic semiconductor, becomes metallic as soon as it is converted into a double layer. The scientists describe the possibility of constructing nanoscale, highly efficient transistors consisting of only one element.

The results of these investigations were published as highlight article in the current issue of the journal Physical Review Letters.

The chemical element phosphorus is considered one of the most essential elements for life...

Though we may not always realize it, photodetectors contribute greatly to the convenience of modern life. Also known as photosensors, photodetectors convert light energy into electrical signals to complete tasks such as opening automatic sliding doors and automatically adjusting a cellphone’s screen brightness in different lighting conditions.

A new paper, published by a team of Penn State researchers in ACS Nano, seeks to further advance photodetectors’ use by integrating the technology with durable Gorilla glass, the material used for smart phone screens that is manufactured by Corning Incor...

Researchers have designed a smart fabric that can detect non-metallic objects ranging from avocadoes to credit cards, according to a study from Dartmouth College and Microsoft Research. The fabric, named Capacitivo, senses shifts in electrical charge to identify items of varying shapes and sizes.

A study and demonstration video describing the sensing system were presented at the ACM Symposium on User Interface Software and Technology (UIST 2020).

“This research has the potential to change the way people interact with computing through everyday soft objects made of fabrics,” said Xing-Dong Yang, an assistant professor of...

Researchers at Los Alamos National Laboratory and their collaborators from the University of California, Irvine have created fundamental electronic building blocks out of tiny structures known as quantum dots and used them to assemble functional logic circuits. The innovation promises a cheaper and manufacturing-friendly approach to complex electronic devices that can be fabricated in a chemistry laboratory via simple, solution-based techniques, and offer long-sought components for a host of innovative devices.

“Potential applications of the new approach to electronic devices based on non-toxic ...
