Researchers at Lawrence Berkeley National Lab have discovered a new semiconductor, rhenium disulphide, that behaves in bulk as if it were a two-dimensional system. At the atomic level, ReS2 can be though of as consisting of stacks of monolayers. Ordinarily, attraction between the monolayers would be strong enough to make the material behave like a 3D semiconductor. But through a mechanism known as the Peierls distortion, rows of adjacent Re atoms acquire kinks that severely weaken the attraction between the monolayers.
