Researchers have demonstrated that electronic interactions play a significant role in the dimensional crossover of semiconductor nanomaterials. The show that a critical length scale marks the transition between a zero-dimensional, quantum dot and a one-dimensional nanowire.
Thanks to a new process, it is now possible to systematically test a large number of chemical reactions in a very small space and within a short time. It enables freely selectable molecules embedded in solid materials to react with each other in a nanometer-sized space.
Being able to determine magnetic properties of materials with sub-nanometer precision would greatly simplify development of magnetic nano-structures for future spintronic devices. In a new article, physicists make a big step towards this goal.
Researchers are pushing the limits of electron microscopy into the tens of picometer scale, a fraction of the size of a hydrogen atom. The ability to see at this subatomic level is crucial in designing new materials with unprecedented properties, such as materials that transition from metals to semiconductors or that exhibit superconductivity.
Scientists can now directly probe a previously hard-to-see layer of chemistry thanks to a unique X-ray toolkit. The X-ray tools and techniques could be extended, researchers say, to provide new insight about battery performance and corrosion, a wide range of chemical reactions, and even biological and environmental processes that rely on similar chemistry.
When it comes to trying to model the properties and behavior of systems of atoms, scientists use two fundamentally different pictures of reality, one of which is called 'statistical' and the other 'dynamical'. The two approaches have at times been at odds, but scientists announced a way to reconcile the two pictures.
Researchers have successfully demonstrated charge transport between Nitrogen-Vacancy color centers in diamond. The team developed a novel multi-color scanning microscopy technique to visualize the charge transport.
