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...]

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...]
