Coupling of electron-hole pairs

Posted by in categories: materials, particle physics

Two-dimensional van der Waals materials have been the focus of work by numerous research groups for some time. Standing just a few atomic layers thick, these structures are produced in the laboratory by combining atom-thick layers of different materials (in a process referred to as “atomic Lego”).

Interactions between the stacked layers allow the heterostructures to exhibit properties that the individual constituents lack.

The coupling of two different electron-hole pairs leads to a fusion of their properties. (Image: L. Sponfeldner, SNI and Department of Physics, University of Basel)
