Researchers in China and at UC Davis have measured high conductivity in very thin layers of niobium arsenide, a type of material called a Weyl semimetal. The material has about three times the conductivity of copper at room temperature.

Stanford researchers redefine what it means for low-cost semiconductors, called quantum dots, to be near-perfect and find that quantum dots meet quality standards set by more expensive alternatives.

While spectroscopic measurements are normally averaged over myriad molecules, a new method developed by researchers at the Technical University of Munich provides precise information about the interaction of individual molecules with their environment. This will accelerate the identification of efficient molecules for future photovoltaic technologies, for example.

A team of researchers led by DOE's Lawrence Berkeley National Laboratory has developed a simple method that could turn ordinary semiconducting materials into quantum machines -- superthin devices marked by extraordinary electronic behavior that could help to revolutionize a number of industries aiming for energy-efficient electronic systems -- and provide a platform for exotic new physics.

Scientists have found a new way to control light emitted by exotic crystal semiconductors, which could lead to more efficient solar cells and other advances in electronics, according to a Rutgers-led study in the journal Materials Today.
