Changing a 2D material's symmetry can unlock its promise

Optoelectronic materials that are capable of converting the energy of light into electricity, and electricity into light, have promising applications as light-emitting, energy-harvesting, and sensing technologies. However, ...

Lab peers inside 2D crystal synthesis

Scientific studies describing the most basic processes often have the greatest impact in the long run. A new work by Rice University engineers could be one such, and it's a gas, gas, gas for nanomaterials.

Scientists now able to map defects in 2D crystals in liquid

Monolayer crystals, often being referred as 2D crystals or 2D materials, possess the unique characteristic of having a single layer of regular atomic structure. And the more regular the structure is, the higher quality the ...

Molybdenum titanium carbide viable in additive manufacturing

Oak Ridge National Laboratory scientists proved molybdenum titanium carbide, a refractory metal alloy that can withstand extreme temperature environments, can also be crack free and dense when produced with electron beam ...

Taking 2-D materials for a spin

Scientists from the University of Tsukuba and a scientist from the Institute of High Pressure Physics detected and mapped the electronic spins moving in a working transistor made of molybdenum disulfide. This research may ...

Smaller, more powerful devices possible with new technique

Shrinking semiconductors even further would enable a whole new silicon revolution. But because that's impossible, the next best hope is integrating semiconductors with 2-D atomically-thin materials, such as graphene, upon ...

How metal atoms can arrange themselves on an insulator

In order to produce tiny electronic memories or sensors in the future, it is essential to be able to arrange individual metal atoms on an insulating layer. Scientists at Bielefeld University's Faculty of Chemistry have now ...

To make a better sensor, just add noise

Adding noise to enhance a weak signal is a sensing phenomenon common in the animal world but unusual in manmade sensors. Now Penn State researchers have added a small amount of background noise to enhance very weak signals ...

A highly light-absorbent and tunable material

By layering different two-dimensional materials, physicists at the University of Basel have created a novel structure with the ability to absorb almost all light of a selected wavelength. The achievement relies on a double ...
