Uncovering How Defects Affect Function in 2D Materials

Scientific Achievement

A team of Foundry staff and users have used a suite of techniques to unravel precisely how defects in tungsten disulfide influence its electronic and excitonic properties.

Significance and Impact

This is the first time that defect effects have been studied in such a detailed way and revealed precisely how they impact the material's properties. The results could open the door to create designer materials by engineering defects for applications in quantum information science or catalysis.
