News and Breakthroughs
Light-twisting materials created from nano semiconductors
Cornell scientists have developed a novel technique to transform symmetrical semiconductor particles into intricately twisted, spiral structures – or “chiral” materials – producing films with extraordinary light-bending properties.
The discovery, detailed in a paper publishing Jan. 31 in the journal Science, could revolutionize technologies that rely on controlling light polarization, such as displays, sensors and optical communications devices.
Revealing the superconducting limit of ‘magic’ material
Graphene is a simple material containing only a single layer of carbon atoms, but when two sheets of it are stacked together and offset at a slight angle, this twisted bilayer material produces numerous intriguing effects, notably superconductivity.
Now Cornell researchers are making headway into understanding how the material achieves this state by identifying its highest achievable superconducting temperature – 60 Kelvin. The finding is mathematically exact, a rare feat in the field, and is spurring new insights into the factors that fundamentally control superconductivity.
Hidden structural states discovered in inorganic nanoclusters
Cornell researchers have uncovered hidden – and perplexing – states in a nanomaterial as it changes its atomic structure, a discovery that could advance materials with tailored properties for renewable energy and quantum computing, among other applications.
The research, published in print Oct. 8 in the journal ACS Nano, is the first to reveal intermediate states in cadmium sulfide nanoparticles as they isomerize, changing from one atomic form to another while keeping their chemical composition.
