While making materials samples to pursue their own research goals, scientists at the U.S. Department of Energy’s Ames Laboratory discovered that an unwanted byproduct of their experiments was an extremely high-quality and difficult-to-obtain substance sought after by scientists researching layered materials.
Bilayer graphene with one of the two layers twisted displayed unique resonant electronic behavior. Understanding how electrons move in such 2-D materials could shed light on how to manipulate them for quantum computing and communication.
Operated by Penn State University’s Materials Research Institute in partnership with Rice University, ATOMIC has won $1.5 million in Phase II funding that will allow it to add both a new academic partner, Boise State University, and new industry partners. ATOMIC currently has 13 industry partners and five government partners.

Graphene, an extremely thin two-dimensional layer of the graphite used in pencils, buckles when cooled while attached to a flat surface, resulting in beautiful pucker patterns that could benefit the search for novel quantum materials and superconductors, according to Rutgers-led research in the journal Nature. Quantum materials host strongly interacting electrons with special properties, such as entangled trajectories, that could provide building blocks for super-fast quantum computers. They also can become superconductors that could slash energy consumption by making power transmission and electronic devices more efficient.
Van der Waals materials that are layered on top of each other are of high interest for electronic and photonic applications. A recent study by Penn State and SLAC National Accelerator Laboratory, in California, provides new insights into the interactions of layered materials with laser and electron beams.
SUMMARYResearchers discovered a new way to engineer optoelectronic devices by stretching a two-dimensional material on top of a silicon photonic platform. Using this method, coined strainoptronics by a team led by George Washington University professor Volker Sorger, the researchers demonstrated…
Researchers from the National University of Singapore have created a new collection of atomically thin two-dimensional materials. Using novel synthesis conditions for transition metal dichalcogenides, more than 10 new materials have been made by the team, with many more still to be discovered.
A team of researchers co-led by Berkeley Lab has observed unusually long-lived wavelike electrons called “plasmons” in a new class of electronically conducting material. Plasmons are very important for determining the optical and electronic properties of metals.
A thin, single layer of graphene material only 1 atom thick may reduce metal pipe corrosion rates as much as 100 times. These new crystalline 2D materials could mean big savings to industries.
The Smithsonian announced today the launch of Smithsonian Open Access, an initiative that removes Smithsonian copyright restrictions from about 2.8 million of its digital collection images and nearly two centuries of data. This means that people everywhere can now download, transform and share this open access content for any purpose, for free, without further permission from the Smithsonian.
