Physicists conduct most precise measurement yet of interaction between atoms and carbon surfaces

UW physicists have conducted the most precise and controlled measurements yet of the interaction between the atoms and molecules that comprise air and the type of carbon surface used in battery electrodes and air filters — key information for improving those technologies.

Scientists craft a semiconductor junction only three atoms thick

As seen under an optical microscope, the heterostructures have a triangular shape. The two different monolayer semiconductors can be recognized through their different colors.

Scientists have developed what they believe is the thinnest-possible semiconductor, a new class of nanoscale materials made in sheets only three atoms thick.

Physicists pinpoint key property of material that both conducts and insulates

The lines of data points are where two of the three solid-state phases of vanadium dioxide can exist stably together, and the point where the three lines meet – the triple point – is where all three phases can exist together.

UW scientists have made the first-ever accurate determination of a solid-state triple point, the temperature and pressure at which three different solid phases can coexist stably.
