A team of researchers at the University of Cambridge, along with the Cambridge-based company Novalia, have produced new graphene-based inks which could lead to high-speed manufacturing of printed electronics. The method involves adding graphene and electrically conducting materials to water-based inks for printing. This is the first time graphene has been used for large-scale … [Read more...]
Laser-Melted Graphite Leads to Linear Chains of Carbon Atoms
Scientists from Lawrence Livermore have discovered a way to generate linear chains of carbon atoms from laser-melted graphite. The material, known as carbyne, has many properties, including the capability of adjusting the amount of electrical current traveling through a circuit. “Its linear shape gives it unique electrical properties that are sensitive to stretching and … [Read more...]
New Technique in Photonic ICs and Optical Computing
A new technique could be a big step toward photonic ICs and optical computing, according to researchers at ITMO University in St. Petersburg, Russia. The technique uses a single silicon nanoparticle as an optical transistor. “In research published in the journal Nano Letters, the Russian scientists turned away from using nanoparticles to control the absorption of light and … [Read more...]
2D Hybrid Perovskites Grown
Researchers at the U.S. Department of Energy's Lawrence Berkeley National Laboratory have grown atomically thin 2D sheets of organic-inorganic hybrid perovskites. These 2D hybrid perovskites are ionic materials that have unique properties, making them possible successors to silicon. “The ultrathin sheets are of high quality, large in area, and square-shaped. They also … [Read more...]
Phosphorene Has Unique Qualities
In 2014, researchers conducted experiments where they exfoliated black phosphorus, or phosphorene, into very thin films of about 10 to 20 atoms thick. Phosphorene, has an inherent bandgap, or energy band in which no electron states can exist, that graphene lacks. According to Philip Feng, an assistant professor of electrical engineering and computer science at Case Western … [Read more...]
