Layered assembly of 2D materials such as graphene have potential roles in the development of new electronic devices.

For the practical application of 2D semiconductors, it is crucial to construct high-quality p-n junctions. Scientist in China developed a low-energy ion implantation system for constructing 2D lateral p-n homojunction.

Move over, graphene. There’s a new, improved two-dimensional material in the lab. Borophene, the atomically thin version of boron first synthesized in 2015, is more conductive, thinner, lighter, stronger and more flexible than graphene, the 2D version of carbon. Now, researchers at Penn State have made the material potentially more useful by imparting chirality — or handedness — on it, which could make for advanced sensors and implantable medical devices.
Two-dimensional quantum materials provide a unique platform for new quantum technologies, because they offer the flexibility of combining different monolayers featuring radically distinct quantum states.
