By taking two flakes of special materials that are just one atom thick and twisting them at high angles, researchers at the ...

This helps to visualise the structure. A two-dimensional model for the ionic lattice in sodium chloride A 2D model shows the arrangement of one layer of ions but it does have a major additional ...

These tools use an extremely sharp probe, sensitive enough to distinguish one atom from another as it scans across a flat surface. The tip of the probe carries an electric charge that enables it ...

Scientists have long known that 2D materials can show vastly different properties from their 3D counterparts, even with the same chemical composition. For instance, a single-atom-thick sheet of ...
