New law for superconductors
MIT researchers have discovered a new mathematical relationship - between material thickness, temperature, and electrical resistance - that appears to hold in all superconductors. They describe their findings in the latest issue of Physical Review B . The result could shed light on the nature of superconductivity and could also lead to better-engineered superconducting circuits for applications like quantum computing and ultralow-power computing.

New 2-D quantum materials for nanoelectronics
Researchers at MIT say they have carried out a theoretical analysis showing that a family of two-dimensional materials exhibits exotic quantum properties that may enable a new type of nanoscale electronics. These materials are predicted to show a phenomenon called the quantum spin Hall (QSH) effect, and belong to a class of materials known as transition metal dichalcogenides, with layers a few atoms thick.

Outsmarting Thermodynamics in Self-assembly of Nanostructures
Outsmarting Thermodynamics in Self-assembly of Nanostructures
If you can uniformly break the symmetry of nanorod pairs in a colloidal solution, you're a step ahead of the game toward achieving new and exciting metamaterial properties. But traditional thermodynamic -driven colloidal assembly of these metamaterials, which are materials defined by their non-naturally-occurring properties, often result in structures with high degree of symmetries in the bulk material.

Solid nanoparticles can deform like a liquid
A surprising phenomenon has been found in metal nanoparticles: They appear, from the outside, to be liquid droplets, wobbling and readily changing shape, while their interiors retain a perfectly stable crystal configuration. The research team behind the finding, led by MIT professor Ju Li, says the work could have important implications for the design of components in nanotechnology, such as metal contacts for molecular electronic circuits.

Excitonic Dark States Shed Light on TMDC Atomic Layers
Excitonic Dark States Shed Light on TMDC Atomic Layers
A team of Berkeley Lab researchers believes it has uncovered the secret behind the unusual optoelectronic properties of single atomic layers of transition metal dichalcogenide (TMDC) materials, the two-dimensional semiconductors that hold great promise for nanoelectronic and photonic applications. Using two-photon excitation spectroscopy, the researchers probed monolayers of tungsten disulfide, one of the most promising of 2D materials, and found evidence for the existence of excitonic dark states - energy states in which single photons can be neither absorbed nor emitted.

Defying physics, engineers prove a magnetic field for light
Defying physics, engineers prove a magnetic field for light
In electronics, changing the path of electrons and manipulating how they flow is as easy as applying a magnetic field. Not so for light. "We don't have such a thing for light," said Michal Lipson, professor of electrical and computer engineering. "For the majority of materials, there is no such thing as something I can turn on, and apply this magic field to change the path of light." Until now.
